Mexican researchers say they created facemask that neutralises Covid-19

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 says.

The 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.

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