Nanotechnologies – tiny devices and systems designed at the nanoscale are developing so fast that regulation of them has been struggling to keep up. In recent years there have been growing fears about the potential risks to human health and the environment from nanotechnology.

Little is known about the risks that nanotechnologies might pose. Animal studies have shown that nanoparticles can penetrate cells and tissues and cause biochemical damage. The use of nanotechnology in defence has raised concerns about effective international arms controls and serious societal consequences. But, despite the public concern, there is little agreement as yet on the most appropriate approach to managing these risks.
