A new antimicrobial surface coating can reduce active microbes on hard surfaces for weeks, according to a study published in the American Journal of Infection Control. Researchers in the Department of Soil, Water and Environmental Science at the University of Arizona in Tucson studied the antimicrobial effectiveness of SurfaceWise by Allied BioScience (ABS) and found that the technology reduced the number of surface bacteria by more than 99 percent for at least eight weeks after the initial application.

The clear coating binds to surfaces and provides a continuous disinfecting action. The study showed positive results in combating a wide range of microbes, including Clostridium difficile, methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococcus (VRE) and carbapenem-resistant Enterobacteriaceae (CRE).

"Cleaning and disinfecting can effectively remove pathogens from surfaces, but studies have shown that more than half the time, surfaces are not adequately cleaned through traditional methods. Plus, these surfaces can be recontaminated within minutes," said Charles P. Gerba, PhD, a professor at the University of Arizona and a member of ABS' scientific advisory board, in a press release. "The study of SurfaceWise has found this technology to continuously keep healthcare environments free of harmful pathogens for up to three months after application."
