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. Plant Extract by Lc-ms/Ms and Evaluation of Medicinal Potentials(Cell Press, 2024) Ipek, Polat; Atalar, Mehmet Nuri; Baran, Ayse; Baran, Mehmet Firat; Ommati, Mohammad Mehdi; Karadag, Musa; Khalilov, RovshanThe Allium turcicum L. (Zuzubak) plant as a cultivated vegetable have various health benefits and consumed as a food. Due to the shortcoming evidence in literature and the importance of this plant in folk medicine, in the present study, for the first time, we evaluated the bioactive profile of components (using LC-MS/MS), cytotoxicity, anticancer, antioxidant, and antibacterial prospectives of Zuzubak methanol extract. Reported results show that the extract is rich in bioactive compounds and has anticancer activity with breast cancer cells (MCF-7), human prostate cancer cells (DU -145), and Human osteosarcoma cancer Cell lines of (IC50) in dose dependent manner in the concentration range of 31.25 mu g/mL and 2000 mu g/mL for 24 and 48 h. 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.Other Citation - WoS: 28Citation - Scopus: 27Removal of cadmium (II) in the aqueous solutions by biosorption of Bacillus licheniformis isolated from soil in the area of Tigris River(International Journal of Environmental Analytical Chemistry, 2021) Baran, Mehmet Fırat; Duz, Mehmet ZahirBiosorption by dead bacteria is an alternative and effective method for the removal toxic elements from drinking water and waste water. The biosorption of Cd(II) from aqueous solutions was studied in a batch method by using dead bacteria Bacillus licheniformis sp. extracted from soil in the area of Tigris River. The Cd element analysis was determined using ICP-OES and AAS. The maximum adsorption capacity of biosorbent was determined, respectively, 24.51 mg/g for Cd element from Langmuir isotherm constants in the optimum conditions. The characterisation of B. licheniformis to describe behaviour of bacteria was determined such as adsorption isotherm, kinetic and thermodynamic data using FT-IR, TGA, DTA, SEM and EDX. The results suggested that the most equilibrium data of Cd(II) bioadsorption was best represented by the pseudo second-order equation and Langmuir isotherm model at different time-temperatures. The thermodynamic functions and activation energy was found to be ΔG°; −0,984 kJ/mol at 318 K, ΔH°; 15.48 kJ/mol, ΔS°; 39.08 kJ/mol and Ea; 23.24 kJ/mol and due to the ΔG°< 0, ΔH°> 0, ΔS°> 0, the reaction mechanism was determined to be physical adsorption and endothermic. This study shows that B. licheniformis sp. can be used as an effective method for the removal of Cd(II) from aqueous solutions.Article Citation - Scopus: 1The interaction methylene blue and glutathione-S-transferase purified from human erythrocytes(Journal of Planar Chromatography - Modern TLC, 2020) Acay, Hilal; Uzan, Serhat; Baran, Mehmet Fırat; Bilden, Alican; Aygün, HüsamettinIt is known that textile dyes have various risks on human health. Glutathione-S-transferase enzymes play a critical role in the detoxification of xenobiotics in living systems. This study aimed to examine the interaction of methylene blue with human erythrocyte glutathione-S-transferase purified in one step. Human erythrocyte glutathione-S-transferase was purified with approximately 750-fold purification and 30% efficiency by glutathione agarose affinity chromatography. The results showed that the enzyme was inhibited by methylene blue with an IC50 value of 1.40 mmol/L. The Ki constant of methylene blue was 1.17 mmol/L. The Lineweaver–Burk graph of the methylene blue showed that the type of inhibition was compatible with mixed type inhibition. A new third spot was also detected by thin-layer chromatography. Furthermore, the cytotoxicity of methylene blue on human erythrocytes was evaluated and it was found that the haemolysis per cent of methylene blue on erythrocytes was approximately 14%.Article GREEN SYNTHESIS, CHARACTERIZATION AND ANTIMICROBIAL ACTIVITY OF SILVER NANOPARTICLES (AgNPs) FROM MAIZE (ZEA MAYS L.)(APPLIED ECOLOGY AND ENVIRONMENTAL RESEARCH, 2019) Eren, abdullah; BARAN, Mehmet FıratIn recent years, the biosynthesis (green synthesis) of metal nanoparticles such as silver nanoparticles (AgNPs) have become one of the safest, most cost-effective and environmentally friendly approaches. In this study, AgNPs were synthesized using maize (Zea mays L.) leaves. For the characterization of synthesized AgNPs different techniques were used, such as X-ray diffraction spectroscopy (XRD), Ultraviolet visible (UV-Vis) spectroscopy, transmission electron microscopy (TEM), Energy dispersive X-ray spectroscopy (EDX), Fourier-transformed infrared spectroscopy (FT-IR) and Thermal gravimetric and Differential thermal analysis (TGA-DTA). The XRD results showed that AgNPs had a mean diameter of 12.63 nm and a crystal-like appearance. In addition, antimicrobial activities of synthesized AgNPs were evaluated using 3 different antibiotics against Gram-negative Escherichia coli and Gram-positive Staphylococcus aureus bacteria and Candida albicans yeast. Antifungal activity of AgNPs with antibiotics has been observed to be better than the antibiotics against Gram-positive and Gram-negative bacteria. The minimum inhibitory concentrations were found to be 0.084, 0.337 and 0.021 mg mL-1 for Escherichia coli, Staphylococcus aureus, and Candida albicans, respectively. The results revealed that AgNPs synthesized from maize leaf extract have antibacterial activity against Gram-negative Escherichia coli, Gram-positive Staphylococcus aureus and antifungal activity against Candida albicans yeast, and that the produced AgNPs could be used in the production of biomedical products and in the pharmaceutical industry.Article Citation - WoS: 26Citation - Scopus: 30Protection of Mild Steel From Corrosion in Hcl Solution Via Green Rumex Acetosella Extract: Experimental and Theoretical Studies(Elsevier, 2024) Arslanhan, Selim; Sigircik, Gokmen; Yildiz, Resit; Baran, Mehmet FiratThe efficiency and potential of green Rumex acetosella extract (RAE) RAE ) on the inhibition of the mild steel (MS) corrosion were investigated in the acidic environment. The high inhibitive capability of RAE on the mild steel was studied by electrochemical impedance spectroscopy (EIS) and linear polarization resistance (LPR) techniques. In addition, potentiodynamic (PD) polarization measurements were carried out to examine corrosion mechanism. The achieved electrochemical tests showed that RAE has a significant inhibition effect on mild steel corrosion. The results of surface analysis recorded by scanning electron microscopy (SEM), and atomic force microscopy (AFM) depicted that RAE provide strong protective layer on the steel surface via adsorptive groups. The inhibition efficiency was calculated as 99.7 %, and 99.6 % from LPR and EIS after 120 h exposure time. Adsorption free energy ( Delta G oads ) value is found as-29.79 kJ mol-1,- 1 , indicating that both physical and chemical adsorptions occur. Furthermore, the obtained experimental findings were supported with quantum chemical calculation results.Article Citation - WoS: 22Citation - Scopus: 25Determination of Antimicrobial and Toxic Metal Removal Activities of Plant-Based Synthesized (capsicum Annuum L. Leaves), Ecofriendly, Gold Nanomaterials(Wiley-v C H verlag Gmbh, 2020) Baran, Mehmet Firat; Acay, Hilal; Keskin, CumaliNanoparticles are valuable materials with widespread use. The fact that these materials are obtained by biological resources with an environmentally friendly method contributes to the development of studies in this field. Gold nanoparticles (AuNPs) from waste vegetable sources (green leaves of Capsicum annum L.) are economically and easily synthesized. The obtained particles are characterized by UV-vis spectroscopy (UV-vis), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and scanning electron microscopy (SEM) analysis. The antimicrobial activity of the particles on the pathogenic microorganisms Escherichia coli ATCC 25922, Staphylococcus aureus ATCC 29213, Bacillus subtilis bacteria, and Candida albicans yeast are found to have a significant suppressive effect. The removal activities of eight toxic metals (Pd, Cd, Fe, Ni, Co, Mn, Zn, Pb) in Diyarbakir drinking water and artificially prepared water within different pHs are investigated. Gold nanoparticles synthesized from Capsicum annuum L. leaves are found to be effective in toxic metal removal in water samples.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 Farklı Biyosorbentler Kullanarak Su Ortamında Ağır Metallerin Biyosorbsiyon Metodu ile Giderilmesi(2022) Düz, M.zahir; Keskin, Cumali; Aktepe, Necmettin; Baran, Mehmet Fırat; Baran, AyşeSu canlılar için ekosistemin önemli parçasıdır. Endüstrileşme ile birlikte su kaynaklarındaki kirlenme endişe edilir boyutlara ulaşmıştır. Ağır metallere bağlı su kirliliği ve artan konsantrasyonları su ekosistemlerine verdiği zarar nedeniyle araştırmacıların konuya olan ilgisinin artmasına sebep olmuştur. Ağır metallerin sularda oluşturduğu kirliliği gidermek ciddi maliyet ve zaman gerektirmektedir. Son yıllarda suda bulunan ağır metallerin uzaklaştırılması için bakteriler kullanılarak biyosorbsiyon yönteminin kullanılması yaygınlaşmıştır. Bu yöntemin tercih edilmesinin temel sebebi gram pozitif bakterilerin hücre duvarında kalın bir peptidoglikan tabakasına sahip olması ile adsorbsiyon kapasitesini artırmasıdır. Bu çalışmada içme, atık, nehir suları ve suni olarak hazırlanan numunelerde çalkalamalı metod kullanarak ağır metal biyosorbsiyonu ile birlikte çoklu hazırlanmış ağır metal çözeltilerinde biyosorbsiyon rekabeti incelenmiştir. Bu işlemler için Dicle nehri bölgesine ait topraklardan izole edilen Bacillus licheniformis sp. Bacillus subtilis sp. ve Bacillus subtilis (ATCC 6051) suşları ile sulu çözeltiden Cd (II), Cu (II), Pb (II), Fe (II), Ni (II) ve Zn (II) metallerinin biyosorbsiyonu değerlendirildi. B. subtilis suşları ve B.licheniformis sp. organizmalarının yüzey morfoljik yapıları SEM görüntüleri, element kompozisyonları EDAX verileri ile incelendi. ICP-OES kullanılarak element içeriği tespit edildi. Sulu çözeltideki Cd (II), Cu (II), Pb (II), Fe (II), Ni (II) ve Zn (II) metal iyonları farklı pH’larda 25 °C de 0,25 mg L-1 biomass ile biyosorbsiyon gerçekleştirildi. pH 6.0 da maksimum biyosorbsiyon ile metal iyonlarının % 98 varan oranda giderildiği belirlendi.Article Citation - WoS: 7Citation - Scopus: 9Silver Nanoparticles for Anticancer and Antibacterial Therapy: a Biogenic and Easy Production Strategy(Wiley-v C H verlag Gmbh, 2025) Dogan, Serap; Baran, Ayse; Baran, Mehmet Firat; Eftekhari, Aziz; Khalilov, Rovshan; Aliyev, Elvin; Smutok, OlehMetal nanoparticles are very valuable products due to their wide range of uses. Among these silver nanoparticles are beneficial products used in many fields, especially in medicine, due to their antibacterial properties. This research aimed to produce silver nanoparticles (Ag NPs) that are both affordable and environmentally friendly. For this purpose, Ag NPs were quickly obtained from domestic waste components of the carrot plant (Daucus carota L.). The UV-vis spectrophotometric, TEM, AFM, FE-SEM, STEM, EDX, XRD, and DLS analyses were performed to determine the properties of the obtained Ag NPs. It has been found that their surface charge is -21.8 mV, with a maximum absorbance at a wavelength of 421.37 nm, spherical appearance, and an average size distribution of 85.41 nm. The anticancer and antibacterial activities of the produced Ag NPs were investigated by MTT and microdilution. The synthesized Ag NPs showed the most significant antimicrobial effect on Pseudomonas aeruginosa ATCC 27833 with microdilution and low concentration. However, they were also determined to be effective on Bacillus subtilis ATCC 11774 and on Candida albicans ATCC 10231 pathogenic strains. In fact, the effective concentrations of Ag NPs on these strains were significantly lower than the antibiotics used. Furthermore, aside from exhibiting a superior anticancer impact on CaCO-2 cancer cells, it was established that Ag NPs also had remarkable efficacy in inhibiting U118 and Skov-3 cancer cells.
