“The coatings, known as “photocatalytic coatings” are usually applied like a spray paint, are not toxic and are very cost-effective. The photocatalytic coating solutions have been used for years in Japan, where they were originally developed to combat air pollution, infectious microbes and soiling of exterior surfaces. When applied, the treated surface oxidizes contaminants in the presence of light. The result is a self-cleaning surface which will degrade any organic substances such as grease, oil, soot or microbes. The result is that the surface remains clean and attractive, instead of becoming soiled or faded”, adds Tseng.
The coating is used in Japanese hospitals to combat disease transmission (e.g., MRSA, Staphylococcus aureus, C. diff.) and reduce sickness in day care facilities and schools, as well as offices and homes. Many people with respiratory illnesses (e.g., asthma, allergies) can benefit.

The photocatalytic coatings are being trialed in British Hospitals. It has been used on door handles which are proving to remain sterile.
