The study of the antibacterial properties of protective paint coatings based on the biocide nanoparticles with non-specific effect on highly pathogenic bacterial strains

Nanotechnologies are increasingly being used as modern methods of combating pathogenic microorganisms in the healthcare sector. Nanoparticles of some metal oxides can have an antibacterial effect, while at the same time remaining safe for cells and tissues of the human body. In this work, we conducted a study of the antibacterial properties of paint and varnish protective coatings created on the basis of a concentrate of ZnO-Ag nanoparticles of relatively highly pathogenic strains of bacteria. As a result, complete inactivation of highly pathogenic strains of bacteria was observed on the surface of the paint and varnish material and paint and varnish composition, including a concentrate of ZnO-Ag nanoparticles. Thus, the coatings under study have antibacterial properties in accordance with R 4.2.3.676-20 and can be used as a means of non-specific protection against the threat of the spread of pathogenic organisms.The authors declare no conflicts of interests.
