The invisible revolution

Abstract:
Molecular-scale machines could one day have medical applications such as removing cancerous cells.

Nanotechnology was originally defined in the 1970s as the science of manipulating atoms and single molecules. Its remit has since expanded to embrace all technologies capable of building structures at the scale of a billionth of a metre. How and why did this change happen and has it affected the field's development?

Politics and big business caused the shift, according to physicist Christian Joachim and journalist Laurence Plévert. In their French-language book they argue convincingly that this more inclusive definition has also altered the initial goals of nanotechnology research.
