Nanotechnology in cosmetics - 2000 years ago...?
These days we are debating if nanoparticles in sunblock and toothpaste are safe. The ancient Greeks and Romans didn't know about such things - but they already used nanotechnology in their cosmetics. A group of researchers in France showed that lead-based chemistry, which was initiated in Egypt more than 4000 years ago, could result in the synthesis of lead sulfide (PbS, galena) nanocrystals.
