Cleaning and Nanotechnology

How can nanotechnology make the products you clean with better?

Nanotechnology companies are finding ways to make the world a cleaner place by exploring three methods for improving cleaning products. These methods are:

Producing films that can be applied to surfaces such as countertops or windows that make it much easier to keep those surfaces clean.
Using nanoparticles in soap that make it work better while producing less environmentally harmful byproducts.
Using materials in the cleaning process that are antibacterial, such as silver nanoparticles. Note that there is interest in regulating the use of silver nanoparticles because of concern that they may harm useful bacteria in groundwater, such as lakes, when released (see Nanotechnology news story below).

Cleaning Products: Nanotechnology Applications

Titanium oxide nanoparticles as part of a long lasting film that uses the energy in light to kill bacteria on surfaces. Titanium oxide nanoparticles are called photocatalysts because of their ability to use energy in light to start the chemical reaction that kills the bacteria.
Customizing the properties of particles a few nanometers in diameter to make a better soap.
A washing machine that uses silver ions to clean clothes.
Customizing the properties of thin polymer layers that you can wipe onto glass to make a long lasting, water repellant film. This technology can make it easier to keep your car's windshield clean and improve visibility when you're driving in the rain.
