Researchers at the University of British Columbia have developed an antibacterial coating consisting of
The researchers showed that the created materialit took just one hour to kill 99.7% of Staphylococcus aureus bacteria. This is twice as fast as pure copper. It is this Gram-positive pathogen that causes the majority of nosocomial infections.
Scientists note that although modern formulations,made from pure copper, have antibacterial and self-disinfecting properties, they kill certain types of bacteria with thicker cell walls (Gram-positive bacteria) more slowly than bacteria with thinner cell walls (Gram-negative).
This coating not only kills pathogens faster,than pure copper, but also helps maintain the effectiveness of antibiotics. Using the new formula, we kill pathogens before patients become infected and need antibiotics. This is how we slow down the growth of antibiotic resistance.

The developers believe that the use of the coatingcan significantly reduce the incidence of bacterial infections from frequently touched surfaces in healthcare facilities and other high traffic areas. Scientists have already registered a patent for the development and promise that the material will be available to hospitals in the near future.
