Nanoparticles Make Surface Too Slippery For Bacteria To Hold
Spitted out by munky on December 29th, 2008. Filed under: ScienceThe researchers adopted polishing technology used in the semiconductor industry (chemical mechanical planarization) to polish the surface of human teeth down to nanoscale roughness. Roughness left on the tooth after the polishing is just a few nanometers, which is one-billionth of a meter or about 100,000 times smaller than a grain of sand.
Bye bye tooth decay!
