Scientists Develop Disinfectant Protecting Surfaces from Coronavirus for 90 Days
TEHRAN (Tasnim) – Researchers at the Hong Kong University of Science and Technology say their new disinfectant spray can "inactivate" up to 99.9% of viruses from surfaces for at least one month, like the one causing COVID-19.
Called MAP-1, the anti-microbial coating has been designed for use across a range of surfaces including glass, metals, plastic, leather and fabrics, according to the Hong Kong University of Science and Technology (HKUST).
The surface coating lasts "significantly longer" than conventional disinfectants that use alcohol or bleach, which loses their function as the liquids evaporates, according to researchers from the university, Cnet reported.
To help do this, it relies on heat-sensitive polymers that its inventors say responds to contamination from touch or droplets. It does this by releasing a larger amount of disinfectant when it senses an increase in temperature that can take place whenever our hands touch a surface or when moisture from droplets.
The anti-microbial spray is expected to hit stores in Hong Kong in May following clinical tests in the city back in February, according to Reuters. Shopping malls, schools and sport training facilities in Hong Kong have used the coating, according to researchers, who also say the ingredients of the coating are non toxic.
The spread of the coronavirus appears to have eased in Hong Kong, where zero new COVID-19 cases were reported several times last week. As of Monday, Hong Kong reported 1,038 coronavirus cases and four deaths.
