Sol-Gel mediated facile synthesis of Zinc-Oxide nanoaggregates, their characterization and antibacterial activity

Abstract

Zinc oxide nanoparticles have been known for their strong antimicrobial properties since a long time. I have synthesized ZnO nanoaggregates using the environment friendly Sol-Gel method. The particles thus prepared were characterized by various technique like UV vis spectrophotometer, X-ray diffraction and Scanning Electron Microscopy. These techniques confirmed the presence of ZnO nanoparticles in form of aggregates. Finally, the antibacterial nature of ZnO nanoaggregates was performed on E. coli MTCC 40 strain of gram negative bacteria using Disk diffusion method.
