New Scientist -- Hospitals could tackle superbugs by painting walls and ceiling with a "killer paint" that destroys bacteria when exposed to light, if preliminary work by UK biochemists works out. Tiny grains of titanium dioxide are used to give white paint its colour because it is very opaque, and very bright. But in 1985, biologists realised that titanium dioxide has more dangerous properties too, at least to bacteria.
