The Study of Antibacterial Properties of Coatins Based on Metal (Ag, Zn) Nanoparticles in Silicon Dioxide Matrix

The influence of coatings on the basis of Ag and Zn metal nanoparticles in a silica matrix in combination with ultraviolet (365 nm) radiation on Staphylococcus aureus 209 P bacteria was studied. It was shown that the investigated coatings without access to light inhibit the growth of microorganisms by 45% after 3 hours of incubation and 55–70% after 5 hours of incubation. Enhancement of antibacterial properties of nanocoatings was achieved by exposure to UV (365 nm) radiation.
