    Activated Carbon-Coated Iron Oxide Magnetic Nanocomposite (ionps@ctac) Loaded With Morin Hydrate for Drug-Delivery Applications
    (Frontiers Media Sa, 2024) Dogan, Yusuf; Ozic, Cem; Ertas, Erdal; Baran, Ayse; Rosic, Gvozden; Selakovic, Dragica; Eftekhari, Aziz
    Cancer is a major disease that affects millions of people around the world every year. It affects individuals of all ages, races, and backgrounds. Since drugs used to treat cancer cannot distinguish between cancerous and healthy cells, they cause systemic toxicity along with serious side effects. Recently, controlled drug-release systems have been developed to reduce the side effects caused by anticancer drugs used for treatment. Morin is an anticancer drug with a flavonol structure. It has been extensively researched for its antioxidant, anti-inflammatory, antitumoral, and antibacterial properties, especially found in Chinese herbs and fruits, and its multiple positive effects on different diseases. In this study, a nanocomposite with magnetic properties was synthesized by coating biocompatible activated carbon obtained using the fruits of the Celtis tournefortii plant on the surface of iron oxide magnetic nanoparticles. Characterization of the synthesized activated carbon-coated iron oxide magnetic nanocomposite was confirmed by Fourier transform infrared, scanning electron microscopy, energy-dispersive X-ray spectrometry, X-ray diffraction, dynamic light scattering, zeta potential, and vibrating sample magnetometry. The cytotoxic effects of the drug-loaded magnetic nanocomposite were examined in HT-29 (colorectal), T98-G (glioblastoma) cancer cell lines, and human umbilical vein endothelial cell (HUVEC) healthy cell line. The morin loading and release behavior of the activated carbon-coated iron oxide magnetic nanocomposite were studied, and the results showed that up to 60% of the adsorbed morin was released within 4 h. In summary, activated carbon-coated iron oxide magnetic nanocomposite carriers have shown promising results for the delivery of the morin drug.

    Altın Nanopartiküllerin Yeşil Sentezi, Karakterizasyonu ve Biyouyumlu Yapılarının Biyomedikal Uygulamalarda (antibakteriyel, Antifungal ve Antikanser) Değerlendirilmesi
    (Kahramanmaras Sutcu Imam Univ Rektorlugu, 2023) Baran, Ayse; Keskin, Cumali
    Gold nanoparticles (AuNPs) stand out due to their low toxicity and high compatibility, and the large and modifiable surface areas they provide. In this study, the leaves of Celtis tournefortii Lam. (CT) were used for the green synthesis of gold nanoparticles (AuNPs) first time. The size, shape, surface charge, and functionality of the synthesized AuNPs are described in detail. The suggested mechanisms of action on the tested target cells are highlighted. The biological activities (antibacterial, antifungal, and anticancer) of "green" AuNPs and their further biomedical application possibilities are also discussed. Synthesized AuNPs displayed a spherical appearance, surface plasmon resonance band at 553.67 nm wavelength, and surface charge of -16.53 mV. Particle morphology, size, and surface charge were observed to be affected by the leaf extract used in the reduction reaction. FTIR and TGA-DTA data revealed that functional groups from the CT extract participate in the synthesis and stabilization of AuNPs. AuNPs showed antibacterial and antifungal effects on all the strains and yeast tested by microdilution method (MIC). AuNPs showed dose-dependent cytotoxic activity on cancerous cell lines (SKOV-3, CaCo2, and U118). The obtained results highlight a potentially low-cost green synthesis method using CT leaf extract to synthesize AuNPs showing important biological properties.

    Antioxidant Properties of allium Turcicum Özhatay & Cowley Plant Extract, Its Effects on the Proliferation and Migration of Cancer Cells
    (Frontiers Media Sa, 2024) Ipek, Polat; Baran, Ayse; Cebe, Deniz Baris; Ahmadian, Elham; Eftekhari, Aziz; Baran, Mehmet Firat
    Cancer is a type of non-communicable disease that is responsible for numerous deaths worldwide. Cancer incidence and mortality rates are on the rise due to a combination of factors, such as a growing population, aging, and poor dietary habits. The Allium turcicum & Ouml;zhatay & Cowley plant is an endemic plant in the area where it grows and is consumed by the public due to its various benefits. This endemic plant, which generally grows in high-altitude regions, is sold in bunches because it is costly, mixed with rock salt, crushed into powder, and consumed as a spice. The cytotoxic and growth-inhibitory effects of A. turcicum & Ouml;zhatay & Cowley herb extract on human glioblastoma U373 cells, human colorectal carcinoma cell HCT-116, and healthy HUVEC cell lines were determined by the MTT method. After 24 and 48 h of application, logIC50 values in HUVEC, HCT-116, and U373 cells were defined as 3.737, 3.765; 3.513, 3.696, 4.476, and 4.104 mu g/mL, respectively. We conducted a cell migration experiment to study the A. turcicum & Ouml;zhatay & Cowley Extract (AT & Ouml;CE) impact on cancer cells' metastatic behavior. Our findings indicate that AT & Ouml;CE has an inhibitory effect on the migration potential of the cells used in the study. We conducted experiments using DPPH, ABTS, CUPRAC, and total phenolic content to assess the antioxidant properties of AT & Ouml;CE. The findings from the antioxidant activity experiments revealed an activity level of 0.20 +/- 0.046 at IC50. Additionally, the total phenolic content was measured to be 0.26 +/- 0.044 mg GAE/g.

    (CMB Assoc, 2023) Zhang, Na; Baran, Ayse; Valioglu, Ferzane; Teng, Lei; Atalar, Mehmet Nuri; Keskin, Cumali; Beilerli, Aferin
    Verbascum thapsus (Mullein) is a medicinal plant used in folk medicine to treat various ailments. For this study, the biological functions of Verbascum thapsus (VT) methanol extract were determined in vitro. The plant's methanol extract was created through the maceration process. The phytochemical composition of plant extracts was investigated using liquid chromatography-electrospray ionization tandem mass spectrometry. The antioxidant capacity of the extract was determined using the 2,2-diphenyl-1-picrylhydrazil (DPPH radical) and 2,2-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS radical). Cell lines Caco-2 (human colorectal adenocarcinoma cells), LNCaP (Lymph Node Carcinoma of Prostate), and HEK293 (Human embryonic kidney 293 cells) were used to model colon, prostate, and non-cancerous cells. The cytotoxic activity of the plant extract on the proliferation of these cells was determined by the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, a tetrazole) assay protocol. VT extract showed moderate DPPH and ABTS radical scavenging activities at 30 mg/ml concentration. With this, VT extract was determined to inhibit acetylcholinesterase (AChE) enzyme and had strong cytotoxic activity on cancerous cell lines. In addition, our findings clearly showed that the plant extract had greater cytotoxic activity on the viability of cancerous cells compared to non-cancerous (Human embryonic kidney cells; HEK293) cells. The current findings showed that V. thapsus might be a promising anti-cancer medication candidate for the treatment of human colorectal adenocarcinoma and colon cancer, as well as a good source antioxidans.

    (Elsevier, 2024) Ipek, Polat; Baran, Ayse; Baran, Mehmet Firat; Eftekhari, Aziz; Khusro, Ameer; Ommati, Mohammad Mehdi; Almutairi, Saeedah Musaed; Fırat Baran, Mehmet; Mehdi Ommati, Mohammad; Musaed Almutairi, Saeedah
    Background: Potentilla fulgens, , a highly valued indigenous medicinal herb grown in high altitudes of the Himalayan region with anticancer, hypoglycaemic, antibacterial, anti-inflammatory, and antiulcerogenic properties, are used in traditional systems of medicine. This study was aimed to investigate the effect of P. fulgens root extract, as one of the natural alternatives to chemotherapeutic drugs used in cancer treatment, on proliferation, apoptosis, and autophagy of human non-small cell lung cancer cell line (A549), human ovarian cancer cell line (SKOV-3), and healthy human umbilical vein endothelial cell line (HUVEC). Methods: Anti-proliferative effect was assessed by MTT assay. The expression of autophagy and apoptosis-related proteins was evaluated by western blotting. Total oxidant status (TOS) and total antioxidant capacity (TAC) test were determined using standard kit methods. Results: Our results showed that the extract inhibited proliferation of HUVEC, A549, and SKOV-3 cells in a dose- dependent manner. MTT assay analysis revealed that the extract significantly (P<0.05) P <0.05) induced mortality in HUVEC, A549, and SKOV-3 cells. Western blot results revealed increased expression of NF-kappa B after the extract treatment but led to the down-regulation in Beclin-1, Bax, extracellular-signal-related kinase 1 and 2, Sequestosome-1, and cleaved Casp-3 levels. Treatment groups showed an increase in TOS and TAC values in A549 and SKOV-3 cell lines, while HUVEC cell line showed an increase in TAC and a decrease in TOS values, compared to the control group. Conclusions: Our findings indicated that P. fulgens root extract inhibited the proliferation of healthy cells and cancer cells through cell cycle arrest, representing its limited application as therapeutic agent in cancer treatment.

    Determination of Chemical Composition and Antioxidant, Cytotoxic, Antimicrobial, and Enzyme Inhibition Activities of Rumex Acetosella L. Plant Extract
    (Springer int Publ AG, 2024) Kandemir, Sevgi Irtegun; Aktepe, Necmettin; Baran, Ayse; Baran, Mehmet Firat; Atalar, Mehmet Nuri; Keskin, Cumali; Khalilov, Rovshan; Irtegün Kandemir, Sevgi
    Purpose The phenolic composition, antioxidant, antimicrobial activity, enzyme inhibition activity, and cytotoxic activity potentials of the plant Rumex acetosella L. (R. acetosella) were examined in this study. Materials and Methods: The chemical composition of R. acetosella methanol extract was identified by the LC-MS/MS method. The antioxidant activity was tested using beta-carotene/linoleic acid, DPPH free radical scavenging, ABTS cation radical scavenging, CUPRAC reducing power, and metal chelating activity methods. The cytotoxic activity was determined by the MTT assay using human ovarian adenocarcinoma (Skov-3), glioblastoma (U87), human dermal fibroblasts (HDF), and human colorectal adenocarcinoma (CaCo-2) cell lines. The antimicrobial activity of methanolic extracts was tested on gram-negative (Escherichia coli and Pseudomonas aeuriginosa) and gram-positive bacteria (Staphylococcus aureus and Bacillus subtilis) using the in vitro minimum inhibition concentration method (MIC). Enzyme inhibition activity of R. acetosella methanol extract was measured spectrophotometrically against acetylcholinesterase (AChE) and glutathione S-transferase (GST) enzymes. Results: The findings showed that the major components of the methanol extract content were luteolin-7-O-glucoside (1.599 m/L), polydatin (91,024 m/L), and shikimic acid (0.773 m/L). It was determined that the extract and standard antioxidant (a-tocopherol) results in DPPH center dot, and ABTS center dot + tests performed to determine the antioxidant activity were close to each other, and this value was more effective than the standard antioxidant (alpha-tocopherol) in the CUPRAC test. These results suggested that the plant's antioxidant potential was higher when compared with reference antioxidant compounds. It was determined that the methanol extract of R. acetosella had a weaker effect on the growth of the tested microorganisms than the antibiotics used as standard. The activity of the GST and AChE enzymes was found to be severely inhibited by the methanol extract of R. acetosella. Conclusion: Based on these findings, R. acetosella L. is a medicinal and commercially beneficial plant that warrants further investigation.

    Development, Characterization and Application of Chitosan-Based Formulation Incorporating Crataegus Orientalis Extract for Food Conservation
    (Jomard Publishing, 2025) Evcil, Murat; Kurt, Barış; Baran, Ayse; Mouhoub, Anouar; Karakaplan, Mehmet
    In this investigation, chitosan-based films loaded with plant extracts from Crataegus orientalis (CR) were elaborated and evaluated in terms of structural, physicochemical and antimicrobial properties. Firstly, the CR extract was characterized by LC-MS/MS showing an abundance of Protocatechuic acid (56.82 μg/g) and Chlorogenic acid (67.13 μg/g). Then, the extract was incorporated into chitosan-based films at different concentrations (CHCR1-3). Findings revealed modifications in FTIR and XRD graphs as well as SEM micrographs following the incorporation of CR extract confirming the changes in the matrix structure and texture. Moreover, the addition of the extract reduced the transparency, swelling ratio, water solubility and moisture content potencies while increasing considerably the material thickness reaching 2.5-fold as regards CHCR3. Furthermore, Thermogravimetric findings showed three stages of degradation for CH control and CHCR2, with mass loss due to water evaporation and glycerol breakdown. Ultimately, CHCR bioformulations showed significant antimicrobial activity against Escherichia coli, Staphylococcus aureus and Candida albicans, especially in the case of the CHCR3, which was verified by the application as a preservative coating for lemon fruit. These encouraging results highlight the potential utilization of CHCR bioformulation as coating/packaging for perishable food products. © 2025 Elsevier B.V., All rights reserved.

    Green synthesis and characterization of selenium nanoparticles (Se NPs) from the skin (testa) of Pistacia vera L. (Siirt pistachio) and investigation of antimicrobial and anticancer potentials
    (SpringerLink, 2023) Keskin, Cumali; Mehmet Fırat Baran, Cumali Keskin, Ayşe Baran, Kadri Kurt, Polat İpek, Aziz Eftekhari, Rovshan Khalilov, Ismayil Fridunbayov, William C. Cho; Baran, Mehmet Firat; Eftekhari, Aziz; Kurt, Kadri; Baran, Ayse; Ipek, Polat; Cho, William C.
    Metallic nanoparticles created by ecologically friendly synthesis processes are becoming increasingly useful in a variety of applications. Because of their strong bioactive component qualities, biocompatible architectures, high stability, and low toxicity, green-produced selenium nanoparticles are particularly signifcant materials for various medicinal applications. Plants include a wealth of essential phytochemicals with therapeutic and medical capabilities. Pistachio vera L. (Siirt pistachio) is a seasonal fruit that is frequently consumed for its nutritional worth and health advantages. However, the outer colored skin of the P. vera (Siirt pistachio) fruit, which is not consumed, contains many biologically active compounds. In this study, plant-mediated synthesis of selenium nanoparticles (SeNPs) was successfully accomplished after adding the sodium selenite solution to the aqueous extract of P. vera colored skin waste. The synthesized Se NPs were characterized with UV–Vis, transmission electron microscopy (TEM), dynamic light scattering (DLS), zeta distribution, atomic force microscope (AFM), Fourier transform infrared spectrum (FTIR), thermogravimetric (TGA) and diferential thermal analysis, X-ray difraction (XRD), and energy-dispersive X-ray spectrum (EDX). Biogenic Pistacia vera (PV) PV-SeNPs were also tested for their ability to suppress the development of various pathogenic bacteria and cancerous cell lines. The UV-visible (UV–Vis) spectra revealed an absorption peak at 325 nm, which refected the surface plasmon band. The signifcant selenium signal on the EDX spectrum at 1.5 keV confrmed the creation of Se NPs. The presence of several peaks on the FTIR spectrum of the aqueous extract of Pv and the nanoparticles indicated the presence of some important functional groups such as amines, carbonyl compounds, and phenols, which are important in facilitating the process of capping and bioreduction, as well as conferring stability to nanoparticles. The TEM microphotographs revealed that the nanoparticles were highly distributed, had a spherical morphological form, and were monodisperse below 10 nm. Biogenic Pv-SeNPs exhibited similar antimicrobial activity as standard antibiotics. However, it was determined that the cytotoxic activity of Se-NPs against cancer cell lines was quite high depending on the dose and time. As a result, the Pv-SeNPs are likely to be extremely benefcial in the pharmaceutical and cosmetic sectors, as well as in the food and cosmetic industries, in producing antimicrobial and/or anticancer medications.

    Green Synthesis and Characterization of Silver Nanoparticles Using Anchusa Officinalis: Antimicrobial and Cytotoxic Potential
    (Dove Medical Press Ltd, 2025) Keskin, Cumali; Aslan, Seyhan; Baran, Mehmet Firat; Baran, Ayse; Eftekhari, Aziz; Adican, Mehmet Tevfik; Mohamed, Ali Jimale
    Objective: Anchusa officinalis L. (A. officinalis) is a herbaceous traditional medicinal plant used in the treatment of some diseases. The presence of its medicinal properties suggested that A. officinalis (AO) leaf extract could be used as a coating agent for the environmentally friendly production of silver nanoparticles (AgNPs). Methods: The synthesized biogenic silver nanoparticles (AO-AgNPs) were characterized using different techniques. The antimicrobial activity of AgNPs against common bacterial pathogenic strains was determined by the minimum inhibitory concentration (MIC) method. The presence of phytochemicals was determined by LSMS/MS. The MTT assay was used to investigate AO-AgNPs' cytotoxic activity in malignant (LnCap, Caco2, MDA-MB2, A549) and healthy (HEK-293) cell lines. Results: LC-MS/MS analysis detected the presence of rich phytochemicals that may be responsible for reduction reactions. Biogenic AO-AgNPs exhibited effective inhibition of the growth of pathogenic microorganisms at low concentrations. The most effective antimicrobial activity was measured as 0.5 mu g/mL MIC against S. aureus, E. coli, and C. albicans. Moreover, AO-AgNPs showed significant inhibition on the growth of cancerous cell lines, especially at a concentration of 25 mu g/mL. On the contrary, it was determined that the inhibition rate decreased in the growth of healthy cell lines due to the increase in concentration. The lowest EC50 values were determined as 15.15 mu g/mL in A549 cells. Conclusion: The obtained results showed that AO could be an important source for the synthesis of AgNPs. Especially their ability to inhibit the growth of antibiotic-resistant pathogenic bacteria at low concentrations compared to common antibiotics indicates that AOAgNPs can be used as biomedical agents in various areas. Moreover, their suppressive effect on cancerous cell lines showed that they have the potential to be used as an anticancer agent, but due to their proliferative effect on healthy cell lines, care should be taken in determining the appropriate dose.

    (Wiley-v C H verlag Gmbh, 2025) Solmaz, Alper; Turna, Talip; Baran, Ayse
    In this study, naproxen (NPX), one of the emerging contaminants was removed by green synthesizing Fe3O4 coated magnetic biochar nanocomposites (Ct-BMNCs) synthesized from Crataegus tanacetifolia Lam. (Ct) wastes. The characteristics of Ct-BMNCs was examined by x-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive x-ray (EDX), Fourier transform infrared spectroscopy (FTIR), thermogravimetry-differential thermal analysis (TGA-DTA), dynamic light scattering (DLS), zetasizer, Brunauer-Emmett-Teller (BET) UV-Vis spectroscopy, and pH point of zero charge (pHpzc). With batch adsorption tests, the effects of pH (4-11), amount of adsorbent (2.5-80 g L-1), time, and initial concentration (3.125-200 mg L-1), and thermodynamic analysis was performed. Also, kinetic and isotherm models and error functions were used. Accordingly, the pHpzc and average surface charge were 5.68 and +11.7 mV, respectively. Moreover, the reaction was exothermic, and the most suitable models were Pseudo-second-order and Freundlich (R2:0.999). Also, qmax was 30.12 mgNPX/gCt-BMNCs. Accordingly, Ct-BMNCs are quite effective in removing NPX.

    Green synthesis of silver nanoparticles based on the Raphanus sativus leaf aqueous extract and their toxicological/microbiological activities
    (SpringerLink, 2023) Hatipoğlu, Abdulkerim; Ayşe Baran, Cumali Keskin, Mehmet Fırat Baran, Aziz Eftekhari, Sabina Omarova, Dawid Janas, Rovshan Khalilov, Mehmet Tevfk Adican, Sevgi İrtegün Kandemir; Baran, Mehmet Firat; Eftekhari, Aziz; Keskin, Cumali; Baran, Ayse; Omarova, Sabina; Kandemir, Sevgi Irtegun
    Silver nanoparticles (AgNPs) have several uses. Many scientists are working on producing AgNPs from plant extracts for use as biomedicines against drug-resistant bacteria and malignant cell lines. In the current study, plant-based AgNPs were synthesized using Raphanus sativus L. (RS) leaf aqua extract. Diferent concentrations of AgNO3 were used to optimize the synthesis process of RS-AgNPs from the aqueous leaf extract. Energy-dispersive X-ray analysis (EDX), transmission electron microscopy (TEM), scanning electron microscopy (SEM), atomic force microscope (AFM), and UV–vis spectroscopy were used to analyze the generated materials. Furthermore, to evaluate the biological properties of the obtained materials, Bacillus subtilis (B. subtilis), Pseudomonas aeruginosa (P. aeruginosa), Staphylococcus aureus (S. aureus), Escherichia coli (E. coli), and Candida albicans (C. albicans) pathogen strains were used for the minimum inhibitory concentration (MIC) assays. Subsequently, healthy cell lines (human dermal fbroblast (HDF)) and cancerous cell lines (glioma/U118, Ovarian/ Skov-3, and colorectal adenocarcinoma/CaCo-2) were engaged to determine the cytotoxic efects of the synthesized NPs. The cytotoxic and anti-pathogenic potential of AgNPs synthesized by the proposed green approach was investigated. The results were encouraging compared to the standards and other controls. Plant-based AgNPs were found to be potential therapeutic agents against the human colon cancer cell (CaCo-2) and showed strong inhibitory activity on Candida albicans and Staphylococcus aureus growth. The RS-AgNPs generated have highly efective antimicrobial properties against pathogenic bacteria. Our fndings also show that green RS-AgNPs are more cytotoxic against cancerous cell lines than normal cell lines. Synthesized nanoparticles with desirable morphology and ease of preparation are thought to be promising materials for antimicrobial, cytotoxic, and catalytic applications.

    (MDPI, 2023) Baran, Mehmet Firat; Beylerli, Ozal; Baran, Ayse; Sufianov, Albert; Yildiz, Resit; Hatipoglu, Abdulkerim; Ipek, Polat
    In the last few decades, the search for metal nanoparticles as an alternative to cancer treatments and antibiotics has increased. In this article, the spectroscopic (ultraviolet-visible (UV-vis), electron-dispersing X-ray (EDX), and Fourier transform infrared (FT-IR)), microscopic (field emission scanning electron microscope (FE-SEM), transmission electron microscope (TEM), and atomic force microscope (AFM)), structural (X-ray diffractometer (XRD) and zetasizer), and analytic (thermogravimetric/differential thermal analyzer (TGA-DTA)) characterization of the silver nanoparticles (AgNPs) produced from Papaver rhoeas (PR) L. leaf extract are presented. PR-AgNPs are generally spherical and have a maximum surface plasmon resonance of 464.03 nm. The dimensions of the manufactured nanomaterial are in the range of 1.47-7.31 nm. PR-AgNPs have high thermal stability and a zeta potential of 36.1 mV. The minimum inhibitory concentration (MIC) values (mg L-1) of PR-AgNPs on Staphylococcus aureus, Escherichia coli, Bacillus subtilis, Pseudomonas aeruginosa, and Candida albicans are 1.50, 0.75, 3.00, 6.00, and 0.37, respectively. In the study, the cytotoxic and proliferative effects of PR-AgNPs using the MTT (3-(4,5-dimethylthiazol-2-yl)-diphenyltetrazolium bromide) method on various cancer cell lines (CACO-2 (human colon adenocarcinoma cell), MCF-7 (human breast cancer cell), T98-G (glioblastoma multiforme cell), and healthy HUVEC (human umbilical vein endothelial cell)) cell lines are presented. After 24 and 48 h of the application, the half-maximum inhibitory concentration (IC50) values (mu g mL(-1)) of PR-AgNPs on HUVEC, CACO-2, MCF-7, and T98-G lines are 2.365 and 2.380; 2.526 and 2.521; 3.274 and 3.318; 3.472 and 3.526, respectively. Comprehensive in vivo research of PR-AgNPs is proposed to reveal their potential for usage in sectors such as nanomedicine and nanochemistry.

    The present work deals with the green synthesis and characterization of silver nanoparticles (AgNPs) using Allium cepa (yellowish peel) and the evaluation of its antimicrobial, antioxidant, and anticholinesterase activities. For the synthesis of AgNPs, peel aqueous extract (200 mL) was treated with a 40 mM AgNO3 solution (200 mL) at room temperature, and a color change was observed. In UV-Visible spectroscopy, an absorption peak formation at ~439 nm was the sign that AgNPs were present in the reaction solution. UV-vis, FE-SEM, TEM, EDX, AFM, XRD, TG/DT analyses, and Zetasizer techniques were used to characterize the biosynthesized nanoparticles. The crystal average size and zeta potential of AC-AgNPs with predominantly spherical shapes were measured as 19.47 ± 1.12 nm and −13.1 mV, respectively. Pathogenic microorganisms Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, and Candida albicans were used for the Minimum Inhibition Concentration (MIC) test. When compared to tested standard antibiotics, AC-AgNPs demonstrated good growth inhibitory activities on P. aeuruginosa, B. subtilis, and S. aureus strains. In vitro, the antioxidant properties of AC-AgNPs were measured using different spectrophotometric techniques. In the β-Carotene linoleic acid lipid peroxidation assay, AC-AgNPs showed the strongest antioxidant activity with an IC50 value of 116.9 µg/mL, followed by metal-chelating capacity and ABTS cation radical scavenging activity with IC50 values of 120.4 µg/mL and 128.5 µg/mL, respectively. The inhibitory effects of produced AgNPs on the acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) enzymes were determined using spectrophotometric techniques. This study provides an eco-friendly, inexpensive, and easy method for the synthesis of AgNPs that can be used for biomedical activities and also has other possible industrial applications.

    Green Synthesis Study: Adsorption of Congo Red Dye With Selenium Nanoparticles Obtained From prunus Armeniaca L. Leaf Waste
    (Wiley-v C H verlag Gmbh, 2024) Turna, Talip; Solmaz, Alper; Baran, Ayse
    In this study, it was aimed to remove Congo Red (CR) dye in aqueous solution by biosynthesized Selenium Nanoparticles from Prunus armeniaca L. (PAL-SeNPs) leaf wastes by green synthesis method. The characteristic structure of PAL-SeNPs was determined by UV-vis spectroscopy, X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET), scanning electron microscope (SEM), energy dispersive X-ray (EDX), fourier transform infrared spectroscopy (FTIR), thermogravimetry-differential thermal analysis (TGA-DTA), dynamic light scattering (DLS), zetasizer, and point of zero charge (pHpzc). The effects of pH, adsorbent amount, time, initial concentration, and temperature were investigated by batch adsorption studies. 2 different kinetic and 4 isotherm models were tested and error analysis functions were determined for the most suitable model. Accordingly, the particle size, crystallinity, pHpzc value and average surface charge of PAL-SeNPs were determined as 9.969 nm, 48.50 %, 3.47, and -23.6 mV, respectively. Also, the most suitable kinetic and isotherm models for the removal of CR dye with PAL-SeNPs were found as Pseudo-second-order and Freundlich, with R2 values of 0.996, respectively. Also, where the optimum pH was 7.00, the maximum adsorption capacity was calculated as 96.59 mgCR/gPAL-SeNPs. The results obtained show that environmentally friendly and low-cost PAL-SeNPs produced by the green synthesis method are a suitable alternative for the removal of CR dye.

    Green-Synthesized Characterization, Antioxidant and Antibacterial Applications of Ctac/Mnps-ag Nanocomposites
    (Mdpi, 2024) Baran, Ayse; Ertas, Erdal; Baran, Mehmet Firat; Eftekhari, Aziz; Gunes, Zubeyir; Keskin, Cumali; Khalilov, Rovshan
    The emergence of antibiotic resistance, caused by the improper use of antibiotics, is a significant challenge in combating infectious diseases, leading to millions of annual fatalities. The occurrence of antimicrobial side effects catalyzes the investigation of novel antimicrobial compounds and sources of drugs. Consequently, the research on biological activity that is conducted on plants, plant extracts, and compounds that are produced from plant components is of utmost significance. In this study, CtAC/MNPs were obtained by the reaction of activated carbon (AC) obtained from the fruits of the Celtis tournefortii (Ct) plant and magnetic nanoparticles (MNPs), and a CtAC/MNPs-Ag nanocomposite was synthesized by the reduction in silver ions added to the reaction. The synthesized CtAC/MNPs and CtAC/MNPs-Ag nanocomposites were analyzed spectroscopically (FTIR, XRD), microscopically (SEM, EDX), optically (DLS), electrochemically (zeta potential) and magnetically (VSM). The antibacterial activities of CtAC/MNPs and CtAC/MNPs-Ag nanocomposites against S. aureus and E. coli were investigated by microdilution method using minimal inhibitory concentration (MIC) and disk diffusion methods. Antioxidant activity study, including total phenolic content and DPPH and cuprac assays, revealed the remarkable effect of the CtAC/MNPs-Ag nanocomposite. This study has the advantages of obtaining CtAC/MNPs and CtAC/MNPs-Ag nanocomposites in a short time without requiring energy, and most importantly, the reaction takes place without using any toxic substances. In addition, according to the data obtained in the study, the CtAC/MNPs-Ag nanocomposite is thought to shed light on biomedical research.

    Green-Synthesized Silver Nanoparticles From Peel Extract of Pumpkin as a Potent Radiosensitizer Against Triple-Negative Breast Cancer (tnbc)
    (Springer Wien, 2024) Montazersaheb, Soheila; Eftekhari, Aziz; Shafaroodi, Amir; Tavakoli, Soodeh; Jafari, Sara; Baran, Ayse; Ahmadian, Elham
    Background: Triple-negative breast cancer (TNBC) is an aggressive subtype of breast cancer. Radiation therapy (RT) is a modality for TNBC management. Radiosensitizers can mitigate the adverse effects of RT. Applying green-synthesized silver nanoparticles (Ag-NPs) from biological sources such as plants is a potential strategy to sensitize cancer cells to radiotherapy due to the low toxicity. Therefore, identifying novel natural sources for synthesizing stable and broadly applicable green-Ag-NPs has gained more attention in cancer therapy. In the present study, we synthesized green- Ag-NPs from pumpkin peel extract and elucidated the impact of green-synthesized Ag-NPs as a radiosensitizer in MDA-MB 231 cells (a model of TNBC). Results: The prepared Ag-NPs had a spherical shape with an average size of 81 nm and a zeta potential of - 9.96 mV. Combination of green-synthesized Ag-NPs with RT exhibited synergistic anticancer effects with an optimum combination index (CI) of 0.49 in MDA-MB-231 cells. Green-synthesized Ag-NPs synergistically potentiated RT-induced apoptosis in MDA-MB-231 cells compared to the corresponding monotherapies. Morphological features of apoptosis were further confirmed by the DAPI-TUNEL staining assay. HIF-1 alpha expression was decreased in cells subjected to combination therapy. Bax and p53 expression increased, whereas Bcl-2 genes decreased. Combination therapy significantly increased the protein level of PERK and CHOP while decreasing cyclin D1 and p-ERK/total ERK levels compared to monotherapies. Conclusion: These findings indicate the potential effect of green-synthesized Ag-NPs as a radiosensitizer for TNBC treatment.

    The Investigation of the Chemical Composition and Applicability of Gold Nanoparticles Synthesized with Amygdalus communis (Almond) Leaf Aqueous Extract as Antimicrobial and Anticancer Agents
    (Molecules, 2023) Keskin, Cumali; Mehmet Fırat Baran, Cumali Keskin, Ayşe Baran, Aziz Eftekhari, Sabina Omarova, Rovshan Khalilov, Mehmet Tevfik Adican, Gvozden Rosić, Dragica Selakovic, Mahmut Yıldıztekin, Kadri Kurt, Canan Aytuğ Ava, Mehmet Nuri Atalar; Baran, Mehmet Firat; Atalar, Mehmet Nuri; Eftekhari, Aziz; Khalilov, Rovshan; Baran, Ayse; Omarova, Sabina
    The current work’s main objective was to determine the chemical composition of Amygdalus communis (AC) leaf extract and examine the antibacterial and cytotoxic properties of biosynthesized gold nanoparticles (AuNPs). The chemical composition of AC leaf extract was determined using LC-ESI/MS/MS to detect compounds that may be responsible for the reducing, stabilizing, and capping steps in the synthesis of nanoparticles and their biological activities. The AC-AuNPs were spherical, with a particle size lower than 100 nm and a face-centered cubic structure. The EDX spectrum confirmed the formation of AuNPs and a negative zeta potential value (−27.7 mV) suggested their physicochemical stability. The in vitro cytotoxic efficacy of the AC-AuNPs against colorectal adenocarcinoma (Caco-2), glioma (U118), and ovarian (Skov-3) cancer cell lines and human dermal fibroblasts (HDFs) was evaluated by MTT assay. CaCo-2 cell proliferation was effectively inhibited by the AC-AuNPs at concentrations between 25 and 100 g mL−1. The AC-AuNPs exerted preeminent antimicrobial activity against Bacillus subtilis with an MIC of 0.02 μg/mL, whilst good activity was shown against Staphylococcus aureus bacteria and Candida albicans yeast with an MIC of 0.12 μg/mL. Ultimately, the results support the high antibacterial and anticancer potential of biosynthesized AuNPs from AC leaf extract.
