In the new study, scheduled for publication in the journal Chemistry of Materials, Dr Walid Daoud of Monash University, Victoria, Australia, and colleagues prepared wool fabrics with and without a nanoparticle coating – particles around five nanometres across (five billionths of a metre) composed of anatase titanium dioxide, a substance already used as a pigment that is known to break down and destroy contaminants upon exposure to sunlight.

“The self-cleaning technology in our work uses titanium dioxide photocatalyst that when triggered by light, it decomposes dirt, stains, harmful microorganisms and so on,” says Dr Daoud.
