Lead oxide (PbO) nanoparticles prepared by a new technique for biomedical applications

Abstract

A simple and convenient method has been demonstrated for large scale synthesis of lead oxide nanoparticles at very low temperatures using water as solvent which is not only benign but also safe. The method is based on a very simple reaction of lead and double distilled water without using any additives or amines. The diameters of the nanoparticles range from 50-150 nm with an average diameter of 100 nm. The formation of nanoparticles by the reaction of metals with water is suggested to occur due to decomposition of water by the metal giving hydrogen. The reported method is fast, economical, environmentally benign and free of pollution, which will make it suitable for large scale production. Moreover, the technique does not require any sophisticated equipments.
