New antimicrobial coating invented to kill 99.9% of pathogens

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

A team of chemists and bioengineers from the Hong Kong University of Science and Technology announced the creation of a versatile clear coat that is suitable for metals, concrete, wood, glass, plastics, as well as fabrics, leather and textiles. After its application, the material does not change its appearance and surface structure.

To create MAP-1, scientists used a special mixture of antimicrobial polymers that works universally and can effectively destroy microbes for three months. The coating also prevents microbial adhesion to the surface, keeping it clean.

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

During a six-month trial at a public hospital and nursing home  MAP-1 has also been shown to be effective against drug-resistant microorganisms. For three weeks of its application on curtains and bed linen, the number of microbes 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 thermoregulatory paint, which can heat the house.
