Abstract

Green chemistry using the extract of plants is one of the cheapest natural methods for synthesizing nanoparticles, which can be taken into consideration along with other physical and chemical methods. In this study, the leaf extracts of Thymus trautvertteri as the reducing agent, was used for the biosynthesis of SILVER NANOPARTICLES. By adding silver nitrate in a concentration of 1 mM to extract, the reaction carried out at room temperature which color change from pale yellow to dark brown was the first visible sign of the synthesis of SILVER NANOPARTICLES. Biosynthesized SILVER NANOPARTICLES were characterized using UV-Visible absorption spectroscopy (UV-Vis), Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), transmission electron microscopy (TEM), and scanning electron microscopy (FESEM). The UV-Visible spectrum showed a peak at 470 nm corresponding to the plasmon absorption of the AgNPs. X-ray diffraction pattern confirmed the formation of crystalline structure of SILVER NANOPARTICLES. FT-IR results also indicated the role of different functional groups in the synthesis process. Transmission electron microscopy (TEM) and scanning electron microscopy (FESEM) analyses shows the synthesized AgNPs are predominantly spherical in shape with average particle size less than 50 nm. Also, the antibacterial properties of nanoparticles against Staphylococcus aureus and Escherichia coli were evaluated by disk diffusion method in Agar, which had a good inhibitory effect on the activity of these bacteria. The proposed synthesis method is eco-friendly and can be potentially used for large-scale production of AgNPs.
