New Paint Based On Titanium Nanoparticles Creates Self-Cleaning Surfaces
hypnosec writes: Scientists have created a paint that provides self-cleaning surfaces and can maintain them even after being wiped, scratched, or scuffed. The paint, composed of titanium dioxide (TiO2) nanoparticles, is delivered as a suspension in ethanol containing the chemical perfluorooctyltriethoxysilane (abstract). Once the coating is applied to a surface, the ethanol must evaporate for 180 seconds before it is ready for use. Depending on the surface, the coating can be sprayed, dipped, or painted.
It sounds so safe and fully tested, here is an MSDS:

What could go wrong with all the NO DATA? /sarcasm
Nano particles can cross the blood brain barrier. What makes you think that's A-OK? Surely that warrants caution at the least?
Lilly pads and similar have a significant nano-structure, not a coating of nano particles.
