The metal nanoparticle synthesis is highly explored the field of nanotechnology. The biological methods seem to be more effective because of slow
reduction rate and polydispersity of the final products. The main aim of this study is too the rapid and simplistic synthesis of silver nanoparticles
by Withania somnifera Linn. at room temperature. The exposure of reaction mixtures containing silver nitrate and dried leaf powder of W. somnifera
resulted in reduction of metal ions within 5 minutes. The extracellular synthesized silver nanoparticles were characterized by ultraviolet-visible,
infrared (IR) spectroscopy, X-ray diffraction studies, zeta potential, Fourier transform IR, and scanning electron microscopy. The antibacterial and
antifungal studies showed significant activity as compared to their respective standards. From the results, W. somnifera sliver nanoparticle has attained
the maximum antimicrobial against clinical pathogens and also seen very good stability of nanoparticle throughput processing. As we concluded, this
type of naturally synthesized sliver nanoparticle could be a better green revolution in medicinal chemistry.
Keywords: Antimicrobial activity, Silver nanoparticles, Withania somnifera.
