[QUOTE="f95toli, post: 6503870, member: 87679"] Probably not. The dangers/properties of nanoparticles are very different from that of bulk materials. Carbon nanotubes are very nasty and need to be handled very carefully whereas a lump of charcoal is not nearly as bad. It is not the material itself that is dangerous: it is the combination of size and shape. Another example is asbestos which is a silicate material which is the most common class of materials on earth. Fortunately, most of them are not nearly as dangerous as asbestos. Also, making gold nanoparticles is not straightforward even in the lab; I doubt any could spontaneously form from a piece of jewellery under normal circumstances. Gold is extremely inert and should be one of the safest materials to use for jewellery. [/QUOTE]
