Nanocosmetics Used Since Ancient Egypt

Roland Piquepaille writes "French researchers have found that Egyptians, Greek and Romans were using nanotechnology to dye their hair several thousands years ago. Nanowerk Spotlight reports they were using lead compounds which generated lead sulfide (PbS) nanocrystals with a diameter of only 5 nanometers. At a moment where many people wonder if the use of nanoparticles is safe, it's good to know that nanotechnology has been widely used for a very long time."

    No no, you can't talk about Roland because you will modded down! He and his many accounts see to that. At least tag this Roland so people with a brain won't waste their time commenting, and mods won't waste time modding down comments like this.!
