HKUST Develops New Smart Anti-Microbial Coating in the Fight Against COVID-19

Researchers at The Hong Kong University of Science and Technology (HKUST) have developed a Multilevel Antimicrobial Polymer (MAP-1) coating that is effective in killing viruses, bacteria and even hard-to-kill spores. MAP-1 can inactivate* up to 99.9 per cent of highly-infectious viruses such as measles, mumps and rubella, and 99.99 per cent 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.

MAP-1 coating is confirmed to be effective against drug-resistant microorganisms during two field studies in the Kowloon Hospital and Haven of Hope Woo Ping Care and Attention Home. Its use in hospital privacy curtains saw over 98.7% reduction in drug-resistant bacteria in 3 weeks. Beyond hospitals, the team works with the Water Supplies Department and the Drainage Service Department to field test MAP-1 in coating materials for water pipes and sewage drainages to prevent microbial contamination and infrastructure corrosion.
