ANTIBACTERIAL ACTIVITY OF VIOLOGEN PENDANT INDOLE STABILIZED SILVER NANOPARTICLES

Abstract

ABSTRACT Synthesis and stabilization of water dispersed silver nanoparticles was achieved by a simple one step procedure using N-methyl-N’-(5-indol-yl-pentyl)-4,4’-bipyridinium dibromide as reducing and stabilizing agent. The viologen pendant stabilized silver nanoparticles were characterized using UV-vis spectroscopy, Transmission Electron Microscope (TEM) and Atomic Force Microscopy (AFM). Further, viologen pendant stabilized silver nanoparticles were studied for antibacterial activity against Staphylococcus aureus, Escherichia coli, Bacillus cereus and Klebsiella nemoniae.
