A Bathroom That Cleans Itself

FiReaNGeL writes "Researchers at the University of New South Wales are developing new coatings they hope will be used for self-cleaning surfaces in hospitals and the home. It's made of a special nanoparticle coating that absorbs ultraviolet light below a certain wavelength and gives the particles an oxidizing quality stronger than any commercial bleach. Say goodbye to tedious bathroom cleaning!"

      No, if this is as powerful an oxidizer as they say, those stains won't form in the first place. The same way oxidizing cleaners break up stains, this stuff would be like having a constant coating of bleach on your bathroom surfaces. Furthermore, due to the "superhydrophilicity" of this titanium dioxide coating (as the article mentions), water will not form droplets (tension cannot be maintained), and thus you have a constant sheeting effect, allowing the surface to be very washable. There's a reason they use this stuff on self-cleaning windows on skyscrapers--it's not for the disinfecting action!
