But it has the potential to revolutionise our lives. Put simply it's science measured on a scale of billionths of a metre. At that level everything, even life, is reduced to fundamental interactions between atoms and molecules. Nanotechnology aims to manipulate and control these particles to create novel structures with unique properties, and promises advances in manufacturing, medicine and computing. But the Canadian based ETC Group claims the potential for harm is equally dramatic. Their report "The Big Down: Technologies Converging at the Nano-scale" argues that because nanotechnology can be applied to virtually any industrial sector, no one regulatory body is taking a lead, and research into new products is continuing beneath the radar screen of public debate.
