This Antimicrobial Coating Kills Coronavirus for 90 Days With a Single Spray

Scientists have found an antimicrobial coating that can keep surfaces clear of SARS-COV-2, the coronavirus which causes COVID-19, for up to 90 days after just a single spray.

Research carried out at the University of Arizona has found that the quantity of the virus on the coated surfaces decreased by 90% in 10 minutes and by 99.9% in 2 hours after one application of the specially formulated coating.

According to Charles Gerba, a microbiologist at the University of Arizona, the finding is the next advancement in infection control:

I think it’s mostly important for high-use surfaces like subways and buses because you could disinfect them but then the next people that come in there will contaminate the surfaces again. It’s not a substitute for regular cleaning and disinfecting, but it covers you in between regular disinfecting and cleaning.

Over the course of the study, Arizona researchers tested various antimicrobial coatings on the Coronavirus 229E which has a genetic structure similar to SARS-COV-2 but it causes only mild cold symptoms.

Researchers found that a coating specially designed by Allied BioScience successfully denatured the proteins of 229E Coronavirus and attacked its outer protective layer of fat.

Charles Gerba has said that antimicrobial coatings on door handles and tabletops will be beneficial once students return to schools and colleges after the lockdown.
