- •Microbial loads on surfaces contribute to health care–acquired infections.
- •Photocatalytic materials destroy organic substances, including microbes.
- •Titanium dioxide is a photocatalytic substance that can be applied as a very safe coating.
- •Infections declined 30% after such a coating was introduced to our facility.
- •Results confirm the logic of the approach and suggest additional studies.
