This spray can protect from virus up to 90 days

Multilevel Antimicrobial Polymer MAP-1

Scientists all over the world are doing many research to protect against Coronavirus. One such research has been done by Hong Kong scientists. Researchers at a University (University of Science and Technology ) of Hong Kong have developed an antiviral coating called (Multilevel Antimicrobial Polymer) MAP-1. Scientists claim that this coating can provide protection from virus-like Coronavirus for up to 90 days.

MAP-1 can inactivate up to 99.9 percent of highly-infectious viruses such as measles, mumps and rubella, and 99.99 percent of the surrogate feline calicivirus (FCV) – a gold standard for disinfection efficiency and is more resistant than coronaviruses such as the one responsible for COVID-19 epidemic.

How MAP-1 Multilevel Antimicrobial Polymer work

MAP-1 coating provides lasting protection and surface disinfection against microbial contamination. This product is designed for use on different surfaces including metals, concrete, wood, glass, plastics as well as fabrics, leathers, and textiles without changing the materials’ appearance and tactile feel. 

According to the Technical Standard for Disinfection issued by the National Health Commission in Mainland China, the coating is proven to be non-toxic and is safe for skin and the environment, hence it also allows MAP-1 to be made into hand sanitizers, paints, and coating, filter materials for air and water purification, as well as clothing and surgical masks to safeguard the health of the individual and public.

MAP-1 is used as a spray. The coating formed after spraying consists of millions of nano-capsules containing disinfectants. Even after spray drying, it is effective in killing bacteria, viruses, and spores. MAP-1 is enhanced by heat-sensitized polymers that disinfect and release upon human contact.

Since scientists had been researching this technique for years, it took 10 years to develop it. Researchers reported that such a coating is used to disinfect various surfaces.

Hong Kong move on MAP-1

This MAP-1 spray was first used in the old AGE CARE home and in Hong Kong hospitals. In February, it was approved for official and large consumer use after several clinical trials.

To deal with the problem like Covid-19, this spray will soon be available in the market of Hong Kong. Apart from this, with the help of government and charity, this spray is being sprayed around the houses of low-income families who cannot buy it.
