Invented a new antimicrobial coating that kills 99.9% of pathogens

Researchers have developed a multi-level antimicrobial polymer coating (MAP-1), which kills most viruses, bacteria and spores, and can also effectively fight COVID-19.

A team of chemists and bioengineers from Hong KongThe University of Science and Technology announced the creation of a universal transparent coating that is suitable for metals, concrete, wood, glass, plastic, as well as fabric, leather and textiles. After its application, the material does not change its appearance and surface structure.

To create MAP-1, scientists useda special blend of antimicrobial polymers thatacts universally and can effectively destroy microbes for three months. The coating also prevents microbial adhesion to the surface while maintaining its cleanliness.

The results of the study showed that the newthe coating can inactivate 99.9% of dangerous viruses, such as measles, mumps and rubella, and 99.99% of surrogate feline calicivirus, which is more resistant than the currently raging coronavirus COVID-19.

During a six-month trial instate hospital and nursing home  MAP-1 has also shown its effectiveness against drug-resistant microorganisms. After three weeks of using it on curtains and bed linen, the number of germs on them decreased by 99% and 95.8%, respectively.

New coatings are being developed not only to fight infections, but also to save energy. Recently, chemists have developed a temperature-regulating paint that can heat homes.
