AP01010 Antibacterial Activity of Manganese Oxide Nanoparticles Prepared by Sol-Gel Method

Abstract

In this study, nanoparticles manganese oxide was prepared by the sol-gel method where solution prepared by dissolving manganese nitrate in distilled water. Urea added to the solution and heated at 140°C for 1 hour to produce MnO₂ gel. The gel dried at 250°C for 1 hour to produce manganese oxide powder. The powder showed that the crystalline system is quaternary with crystallite size of 33 nm. The antibacterial activity of MnO₂ nanopowder was studied against two kinds of bacteria (Escherichia coli and Klebsiella). MnO₂ nanopowder showed good antibacterial activity.
