Green synthesis and characterization of silver nanoparticles from withania somnifera (L.) Dunal

Abstract

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.
