Nanotechnology is significantly influencing science and economy in the 21st century. plant mediated synthesis of nanoparticle is a green chemistry approach that interconnects nanotechnology and plant biotechnology. Silver nano particles are promising agents in bionanotechnology, because of their unique activity against unfavorable processes in bioscience such as undesirable microbial growth. This study presents a safe method of silver nanoparticles (Ag NPs) preparation by green synthesis approaches that have advantages over contractual methods involving chemical agents associated with environmental toxicity. Green synthesis of nanoparticles will became is very importance field in nanotechnology. In this study leaf extract of Thymus vulgaris were used to synthesize silver nanoparticles.The silver nanoparticles were characterized by UV-Visible, X-ray diffraction (XRD), Fourier transform infra-red spectroscopy (FT-IR) and transmission electron microscopy (TEM) techniques.TEM analysis of silver nanoparticles showed formation of spherical shapes in the size range 9–78 nm. The characterized nanoparticles of Thymus vulgaris potential for various medical and industrial applications.
