Study on the effect of zinc oxide nanopowder doped with different concentrations of cobalt, on the properties of implants

Abstract

The aim of this study was to improve the physical, mechanical and chemical properties of biomaterials used in medical applications, by depositing thin films with superior properties on the surface of the materials. Starting from the antibacterial effect of ZnO nanopowders, doped or not with different concentrations of cobalt, five thermally treated thin films were deposited at 500°C, on a metallic titanium substrate, by the spin coating technique, a simple method that does not involves too many costs of depositing thin films on metal surfaces, starting from precursor liquids that gel over time. From the analysis of the resulting films, from a compositional, microstructural, morphological point of view, an increase in the antimicrobial activity of the materials used in impantology was found.
