Research team from Division of Environment and Sustainability at HKUST, has developed a Multilevel Antimicrobial Polymer (MAP-1) coating that is effective in killing viruses, bacteria and even hard-to-kill spores. 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. 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.
