HKUST Engineers Develop Antiviral Coating to Protect Surfaces from Coronavirus like Viruses

Researchers at a Hong Kong university say they’ve developed an antiviral coating which could provide 90 days of important safety against bacteria and viruses such as the one causing COVID-19.

The coating, referred to as MAP-1, took ten years to develop and will be sprayed on surfaces that are continuously utilized by the public, such as elevator buttons and handrails, researchers at the Hong Kong University of Science and Technology (HKUST) say.

The coating that forms after spraying has millions of nano-capsules containing disinfectants, which Kwan says stay efficient in killing microorganisms, viruses, and spores even after the coating has dried.

Unlike common disinfecting strategies such as diluted bleach and alcohol, MAP-1 is further boosted by heat-sensitive polymers that encapsulate and release disinfectants upon human contact, Kwan stated.

Following clinical tests this year at a Hong Kong hospital and a home for the aged, the coating has been made available for business purchases by Germanic, a subsidiary of the university’s industrial partner, Chiaphua Industries Ltd.

The coating was accredited for official and mass consumer use in February and will hit Hong Kong shops next month.

With help from a local charity, the non-poisonous coating has already been sprayed across the homes of over a thousand low-income households in the metropolis.

The researchers stated shopping malls, schools, and sports training in the city had adopted the coating.
