MgO nanostructures: Formation and Antibacterial Activity

An improved and non toxic way for the preparation of magnesium oxide (MgO) nanostructures having size range of 60 ± 15nms has been established at very low temperature of ~ 125°C. The formation of nano particles by the reaction of metals with water is suggested to occur due of decomposition of water by the metal giving hydrogen. The approach described can potentially eliminate the problem by making nano particles non toxic and biocompatible. Bactericidal experiments with gram positive and gram negative were carried out using as synthesized MgO nano particles and their bactericidal mechanism was investigated.
