There are plenty of guidelines implementing, including hand hygiene guidelines, Multi-drug Resistant Organisms (MDROs) infected patient treatment policy to avoid cross infection of MDROs. However, it hard to adhere to these guidelines due to many reasons. The smart antimicrobial coating is designed to provide a sustainable release of antimicrobial agent to provide a long-term protection to surface. The antimicrobial coating is designed to use a water in oil in water emulsion structure to encapsulate chlorine dioxide such that the biocide can be released slowly to the environment. The coating was applied to a local hospital in Hong Kong. Our study showed that there was desirable reduction of biological contamination on the surface involved in this study compared to the normal cleaning regime. The result has indicated the feasibility of an improved cleaning regime. The add-on effect of antimicrobial activity towards existing furniture is a workable solution for reducing nosocomial infection.
