“…When the biomolecules involved in reduction during the formation of AgNPs were examined ( Figures 5A,B ), the absorption peak at 1635 cm −1 corresponded to the C=O stretching vibration, indicating the presence of amide. Because of the phenolic compounds in the CA leaf extract, it can be concluded that the absorption peak at 2122 cm −1 belongs to alkyne (C≡C) groups while the absorption peak at 3331 cm-1 belongs to O-H and N-H stretching ( Atalar et al, 2021 ). Presumably, these determined functional groups are responsible for the reduction of metal ions ( Mandal et al, 2015 ).…”

Using biological materials to synthesize metallic nanoparticles has become a frequently preferred method by researchers. This synthesis method is both fast and inexpensive. In this study, an aqueous extract obtained from chickpea (Cicer arietinum L.) (CA) leaves was used in order to synthesize silver nanoparticles (AgNPs). For specification of the synthesized AgNPs, UV-vis spectrophotometer, Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction analysis (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), electron dispersive X-ray (EDX), and zeta potential (ZP) analyses data were used. Biologically synthesized AgNPs demonstrated a maximum surface plasmon resonance of 417.47 nm after 3 h. With the powder XRD model, the mean crystallite dimension of nanoparticles was determined as 12.17 mm with a cubic structure. According to the TEM results, the dimensions of the obtained silver nanoparticles were found to be 6.11–9.66 nm. The ZP of the electric charge on the surface of AgNPs was measured as −19.6 mV. The inhibition effect of AgNPs on food pathogen strains and yeast was determined with the minimum inhibition concentration (MIC) method. AgNPs demonstrated highly effective inhibition at low concentrations especially against the growth of B. subtilis (0.0625) and S. aureus (0.125) strains. The cytotoxic effects of silver nanoparticles on cancerous cell lines (CaCo-2, U118, Sk-ov-3) and healthy cell lines (HDF) were revealed. Despite the increase of AgNPs used against cancerous and healthy cell lines, no significant decrease in the percentage of viability was detected.

Objective: In this study, CS-AgNPs were synthesized, characterized, and antimicrobial activity evaluated by using the extract obtained from the purple flower parts of the waste saffron flower with an economical, easy and environmentally friendly method. Method: In this study, green, economical and rapid synthesis of silver nanoparticles (AgNPs) was carried out using Saffron (Crocus sativus (CS)) purple flower extract. For structure elucidation of silver nanoparticles synthesized with saffron flower extract (CS-AgNPs); UV-visible (UV-vis.) Spectrophotometer, Fourier Scanning Electron Microscope (FE-SEM), Scanning Electron Microscope (SEM), Electron Distributed X-rays (EDX), Fourier Transform Infrared Spectroscopy (FT-IR), X-Ray Characterized using Diffraction Diffractrometer (XRD), Transmission Electron Microscope (TEM), Zeta potential data. It was determined that the UV-visible spectrum of the biologically synthesized silver nanoparticles, the spectrum taken after 15 minutes was formed at the maximum wavelength of 405.68 nm. In addition, it was observed that the UV spectrum of the synthesized nanoparticles, taken one month later, gave the same wavelength, and the obtained nanoparticles were stable. Antimicrobial activities of CS-AgNPs were evaluated on gram-positive, gram-negative and fungal strains using the minimum inhibition concentration technique. Results: As a result, it was determined that the obtained CS-AgNPs showed activity on bacterial and fungal strains. Conclusion: It was observed that the smaller the size of the silver nanoparticles obtained, the greater their antimicrobial activity and strong antibacterial and anticandidal activity even at very low concentrations.

“…SEM is a powerful electron microscope and a popular surface imaging technique. SEM produces a high-resolution, magnified three-dimensional image and provides information on the purity of the sample (Atalar et al, 2021). It magnifies images using electrons rather than light, as conventional microscopes do (Sharma et al, 2019).…”

“…This new method reduces the toxic effects of NPs produced by conventional (physical and chemical) methods. In addition, green synthesis is preferred as a better alternative to physical and chemical methods in the production of nanoparticles due to its numerous advantages such as simplicity, rapid synthesis, biocompatibility, environmental friendliness and low cost (Atalar et al, 2021;Gour and Jain, 2019). The green synthesis method is commonly used to synthesize metallic nanoparticles such as silver, gold, cadmium, copper, zinc, and platinum.…”

Rumex 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.
