Scientists claim this new disinfectant protects any surface from Coronavirus for 90 days

The Hong Kong University of Science and Technology researchers have created a new disinfectant spray and claim it can “inactive” virus for 90 days from the surfaces, including the COVID-19 virus.


Researchers at the top university of Hong Kong have developed a new disinfectant or anti-microbial coating that is sprayed on the surface to kill viruses and bacteria, including the novel Coronavirus- and can protect the surface for 90 days.

This anti-microbial spray is known as MAP-1 and is designed to be used across different surfaces like metals, glass, leather, fabrics, and plastic, according to Hong Kong University of Science and Technology (HKUST).

The surface coating of these disinfectants lasts significantly longer than the usual disinfectants, which are made with alcohol and bleach and lose their function as soon as the liquid evaporates, said HKUST. 

Ton achieve this result, it depends on heat-sensitive polymers, the inventor of the disinfectants says that it responds to the contamination from droplets or touch. It releases a large amount of disinfectant whenever it senses any increase in temperature that takes place when our hands touch the surface or with the moisture from the droplets.

This anti-microbial coating is set to be available in stores of Hong Kong in May after following a clinical test done in February in the city. Schools, shopping malls, sports training facilities, and churches in Hong Kong have tested and used this disinfectant spray, according to the researchers, and they also say that the ingredients used are non-toxic. HKUST avoided making an immediate response to the request for any comments on whether there is any plan for MAP-1 to be made available for sale in the US and other countries.

The spread of novel Coronavirus seems to have eased in Hong Kong. There are no new cases of COVID-19 reported for several days last week. Till Monday, 1,038 cases of Coronavirus have been reported in Hong Kong and four death due to COVID-19.
