Researchers at the National Autonomous University of Mexico (UNAM) have created a facemask using silver and copper nanolayers that neutralises SARS-CoV-2, the virus that causes COVID-19, the university’s official gazette said on Thursday.

UNAM is calling the triple-layered antimicrobial facemask SakCu; Sak means silver in Mayan and Cu is the chemical symbol for copper.

To test the mask, researchers took drops with the virus from COVID-19-positive patients at the Hospital Juarez in Mexico and placed them on the silver-copper film deposited in polypropylene.

UNAM said that if the viral concentration was high, the virus disappeared by more than 80% in about eight hours and if the viral load was low, in two hours none of the virus RNA was detected.
