Transparent bactericidal ZnO nanocoatings

Abstract

Thin bactericidal ZnO coatings prepared with the polymer-salt method are shown to be highly transparent in the visible. The spectral measurements and XRD analysis data show that coatings prepared are formed by ZnO nanoparticles ~ 10 nm in size. The coatings demonstrate the bactericidal effect against the gram-positive Staphylococcus aureus ATCC 209P and gram-negative Escherichia coli ATCC 25922 bacteria both under the natural light and in the darkness.
