Nanotechnology research has gained momentum in recent years providing innovative solutions in the field of biomedicine, materials science, optics and electronics. Essentially, nanoparticles are a varied form of basic elements, which are derived as a result of a change to the atomic and molecular properties of the required elements. This article provides further detail on the properties and applications of zinc oxide nanoparticles (ZnO).

ZnO nanopowders are available as powders and dispersions. They exhibit antibacterial, anti-corrosive, antifungal and UV filtering properties. Zinc is a Block D, Period 4 element, while Oxygen is a Block P, Period 2 element. Some of the synonyms used for ZnOs are oxydatum, zinci oxicum, permanent white, ketozinc and oxozinc.
