The Self-Cleaning Bathroom Still on the Drawing Board

Earlier this year, I told you about one of the handiest uses for nanotechnology in the near future: Cleaning bathrooms lined with a thin coating of titanium dioxide. The only limitation to that process has been the lack of ultraviolet sunshine that can activate the cleaning process.

Australian scientists are attempting to get around that problem by formulating a product similar to PPG Industries' TiO2 line of self-cleaning agents. Only this time, however, the self-cleaning chemicals would be activated by the visible spectrum of light, namely the light bulb.

Figuring out how to get the job done without sunlight won't be easy, scientists say, without altering the chemical's inert features. Any miscalculation, and the chemical may not stay where it's intended.

No doubt, folks, nanotechnology will change our lives in the future, for better or worse. That said, I don't believe there will be any risk in using products powered by nanotechnology, but there could be major health problems in store for the people who make them.
