Catalytic cotton chows down on dirt.: “In the classic 1951 film, The Man in the White Suit, Alec Guinness played a scientist who invents a fabric that never gets dirty or wears out. A chemist’s pipe dream perhaps, but the prospect of self-cleaning clothes might be getting closer.

Scientists have invented an efficient way to coat cotton cloth with tiny particles of titanium dioxide. These nanoparticles are catalysts that help to break down carbon-based molecules, and require only sunlight to trigger the reaction. The inventors believe that these fabrics could be made into self-cleaning clothes that tackle dirt, environmental pollutants and harmful microorganisms.” (Nature)
