Still Dyeing After 2,000 Years
Abstract:
Nanotechnology may seem like the latest fad in beauty products, but a new report suggests that people have been using nanomaterials to improve upon nature for at least 2,000 years. According to researchers in France, an ancient hair-coloring concoction turns tresses black via the formation of lead sulfide nanoparticles within the hair shaft.
