Abstract

A green synthesis of silver nitrate nanoparticles was carried out using Vitis vinifera skin peel extract. Synthesized nanoparticles were characterized using UV-Vis absorption spectroscopy, DLS, TEM, FT-IR and XRD studies respectively. UV-Vis absorption spectroscopy of prepared silver nitrate colloidal solution showed absorption maxima at 360 nm. TEM and analysis showed average particle size ranges from 0.2-0.5μm whereas SEM shown 400μm, while XRD confirms SAED pattern confirmed the crystalline nature of synthesized nanoparticles. FT-IR analysis indicated the involvement of hydroxyl (O-H), nitrates, carboxylic acids and amine (N-H) functional groups of Vitis vinifera peel extract in preparation of silver nitrate nanoparticles. DLS shows the particle size of silver nitrate nanoparticles is 91.6nm and zeta potential is -20.7mV. Hence from this study we concluded that the nanoparticles synthesized from Vitis vinifera peel extract has shown very effective on in-vitro antimicrobial activity (Gram positive and negative Bactria, Fungi) using disc diffusion method.
