Researchers from Hong Kong University of Science and Technology say they have developed a new type of disinfectant spray that will continue killing bacteria and viruses — including coronavirus — for 90 days after application.

The substance is an anti-microbial coating called MAP-1. It contains polymers that are heat-sensitive and will release more disinfectant when it senses heat on the surface to which it has been applied, such as a droplet of spit landing on the surface or the touch of a hand. The inventors of MAP-1 say it is made with non-toxic ingredients.

The substance already has been tested in hospitals, schools, shopping malls, and other locations throughout Hong Kong. It is slated for release to the Hong Kong market in May. No information is available on when MAP-1 may be accessible outside of Hong Kong.
