EVALUATION OF ANTIBACTERIAL ACTIVITY OF BIOSYNTHESIZED Ag-Au NANOCOMPOSITE USING VITIS VINIFERA FRUIT EXTRACT

Abstract

This report is an environmentally friendly biosynthesis method for the synthesis of Ag-Au bimetallic nanoparticles (Ag-Au NCP) from the equimolar solution of silver (I) nitrate and gold (III) chloride using Vitis vinifera fruit extract as a "green" reducing agent. This is a single-pot procedure and it doesn’t involve any surfactant, template, and capping agent towards stabilization of nanoparticles. The crystallinity and morphology of the synthesized Ag-Au bimetallic nanocomposites were characterized using SEM, TEM, EDX, XRD, and FTIR. Additionally, the evaluation of antibacterial activity has been studied.
