Researchers at a Hong Kong university say they have developed an antiviral coating that could provide 'significant' protection against bacteria and viruses such as the one causing COVID-19
HONG KONG - Researchers at a Hong Kong university say they have developed an antiviral coating which could provide 90 days of “significant” protection against bacteria and viruses such as the one causing COVID-19.
The coating that forms after spraying has millions of nano-capsules containing disinfectants, which Kwan says remain effective in killing bacteria, viruses and spores even after the coating has dried. With help from a local charity, the non-toxic coating has already been sprayed around the homes of more than a thousand low-income families in the city.
