A new nano-coating was created in Russia to suppress the growth of bacteria and fungi. This was reported by the press service of NUST MISIS, where the technology was developed.
“We have synthesized coatings consisting of boron nitride nanoparticles interspersed with ultrafine silver or iron oxide nanoparticles. Second, it effectively inhibits the growth of Escherichia coli as well as Staphylococcus aureus and pneumococci. Coatings containing minimal concentrations of silver completely inactivate bacteria,” said Kristina Gudz.
Metal ions destroy microbes when they get into their shells. Zinc and copper oxides have a particularly strong antimicrobial effect, and therefore compounds based on them are used in deodorants or for coating medical instruments. Russian experts have found a way to inexpensively create such coatings with high antimicrobial activity. These coatings are based on needle-shaped boron nitride nanoparticles that allow them to interact better with membranes. Its properties are enhanced by iron and silver nanoparticles.
As a result, it turned out that even at low metal ion concentrations (12 and 72 micrograms per square centimeter), such coatings provide 99% protection against microbes. In the near future, the authors will create a dressing material based on this technology and check whether such a coating helps against cholera and coronavirus.
