Dealing with things smaller than 100 nanometres (for comparison, a human hair is 80 000 nm wide), nanotechnologies are fast becoming the 'next big thing' (only not so big at all). Yet while nano-enthusiasts say they are the future, nano-sceptics are concerned about potential dangers. From nano-hype to nano-nonsense, this issue in the 'Big Picture' series sifts sense from speculation. What are nanotechnologies and what might they do for us? What (if anything) do we need to worry about? How are potential benefits weighed against possible downsides? What role should the public play in the process of nano development?
