Article Citation - Scopus: 4Inhibitory effects of gold nanoparticles biosynthesized by redox reaction using Rheum ribes lam fruit peels on pathogen strains and cancer cells(Particulate Science and Technology, 2023) Baran, AyşeGold nanoparticles (AuNPs) are very valuable materials used in many fields, especially in biomedical applications. In this study Rheum ribes Lam-derived AuNPs (Rrib AuNPs) were synthesized in an environmentally friendly, easy and low-cost method using the extract obtained from the waste skin of the fruit known as Rheum ribes Lam (Kurdish banana). Functional groups of phytochemicals responsible for redox reactions were determined by FTIR data. Properties of synthesized Rrib AuNPs UV-vis, TEM, FE-SEM, Zeta potential, XRD, AFM, TGA-DTA), EDX), Zetasizer devices. In the characterization data, it was determined that Rrib AuNPs had an average size distribution of 58.27 nm, a spherical appearance morphology, a maximum absorbance of 543.96 nm, a surface charge of 23.0 mV, a monodisperse and stable structure. It was determined by microdilution that the synthesized Rrib AuNPs had antibacterial and anti-fungal effects with 0.03–0.50 mg ml1 Minimum Inhibition Concentration amounts. The cytotoxic effects of Rrib AuNPs on cancer and healthy cell lines were investigated using the MTT method.Article Citation - Scopus: 39Development, 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, MehmetIn 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.Article Citation - WoS: 27Citation - Scopus: 33Green 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 JimaleObjective: 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.Article Citation - WoS: 8Citation - Scopus: 10Determination of Chemical Components of the Endemic Species allium Turcicum L.

Western blotting results determined that the extract significantly suppressed the growth of U2OS, MCF-7, and DU -145 cancer cells by down expression of Ang-1 (angiogenic protein) and Beclin-1 (autophagy protein) and overexpression of Bax (a proapoptotic protein). The oxidative stress indices showed a reduction in RPE-1 and MCF-7 cells and an upsurge in U2OS and DU -145 cells. Additionally, the antimicrobial assay showed suppression of the growth of various pathogenic microorganisms in 4.00 - 8.00 mu g/concentrations of Zuzubak extract using the microdilution method. The phytochemicals identified showed promising anticancer, antioxidant effects, and antimicrobial properties, representing a valuable herbal source for drug development studies.Article Synthesis, Characterization and Evaluation of Antimicrobial Activities of Silver Nanoparticles Obtained From Rumex Acetosella L. (sorrel) Plant(2022) Aktepe, Necmettin; Bütüner, Hafize; Baran, Ayşe; Keskin, Cumali; Baran, Mehmet FıratRumex acetosella L. (sorrel) is a plant belonging to the Polygonaceous family and is a species that grows naturally across Turkey. In this study, the characterization of silver nanoparticles (AgNPs) obtained from the Rumex acetocella L. (RA) plant using the green synthesis method was performed and their antimicrobial activities were investigated. AgNPs were successfully synthesized in the first stage of the study using plant extract taken from plant samples collected from the natural growing environment. Characterization of synthesized AgNPs was performed using appropriate analytical methods (UV-vis, FT-IR, XRD, SEM-EDX, TEM, Zeta Potential and Zeta Sizer). According to the analysis results, it was determined that AgNPs had a maximum absorbance at 476 nm wavelength, a pentagonal, hexagonal, and spherical appearance, a size of 29.16 nm, and a zeta potential of -9.88 mV. The antimicrobial activities of AgNPs were tested using the microdilution technique, in which Minimum Inhibition Concentration (MIC) values were determined on gram-positive Staphylococcus aureus, Bacillus subtilis and gram-negative Pseudomonas aeruginosa, Escherichia coli bacteria and Candida albicans fungus. It showed a very strong antimicrobial effect on C. albicans, S. aureus and P. aeruginosa. Consequently, AgNPs had stronger antimicrobial activity at low concentrations and when compared to commercial antibiotics.Article Citation - WoS: 12Citation - Scopus: 13The 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, SabinaThe 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.Article Citation - WoS: 6Citation - Scopus: 7Green 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, AyseIn 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.Article Gümüş Nano Malzemelerin Çevre Dostu, Hızlı Sentezi ve Biomedikal Uygulamaları(2021) Baran, AyşeBu çalışmada, ceviz yaprakları kullanılarak hazırlanan özüt ile gümüş nano malzemeler çevre dostu hızlı ve basit bir şekilde sentezlendi.

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, SevgiPurpose 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.Article Citation - WoS: 69Citation - Scopus: 74Ecofriendly Synthesis of Silver Nanoparticles Using Ananas comosus Fruit Peels: Anticancer and Antimicrobial Activities(Hindawi, 2021) Baran, Ayşe; Keskin, Cumali; Baran, Mehmet Fırat; Huseynova, Irada; Khalilov, Rovshan; Eftekhari, Aziz; Irtegun-Kandemir, Sevgi; Kavak, Deniz EvrimMetallic nanoparticles are valuable materials and have a range of uses.
