Scientists from the Perm National Research Polytechnic University (PNRPU) have found a new and effective way to disinfect surfaces in hospitals. This provides longer-lasting protection against pathogens compared to existing methods, the scientific institution told socialbites.ca.
Polytechnicians created a polymer-based composition using zinc and copper salts as antibacterial agents. Metal nanoparticles were embedded in polyacrylamide (PAA), which is used to gel liquids and form films. The researchers then examined how the finished metal-polymer preparation copes with microbes.
The scientists selected several strains of pathogenic microorganisms and tested them for interaction with copper and zinc solutions at concentrations between 0.075% and 5% in a polymer medium.
Experiments have shown that polyacrylamide cannot serve as a breeding ground for pathogens commonly seen in hospitals, while the addition of metal nanoparticles inhibits the growth and activity of bacteria. Researchers have found that the polymer base helps significantly increase the disinfection area. The scientific institution noted that this technology has not been used anywhere before.
Previously in Russia was created coating that disinfects surfaces using light.
