nanotoxicology. There has been a lot of research into the risks of using nanotechnology, most of these are explained below.Although the “nano boom” could contribute a lot to the society of the future, there are several health risks involved with using nanoparticles. The study of toxicity in nanomaterials, is called
A rather more far-fetched theory about a possible risk of the use of nanotechnology is the notion of the by-product of 'grey goo'. The theory is a hypothetical situation where simply put, 'out-of-control self-replicating robots' take over Earth, by consuming all matter.
