What exactly is Nanotechnology?
Although it is of course no guarantee of being 100% correct, with questions like these it is always interesting to have a look at the wiki entry on the subject.
(be careful with Wiki, though if you need accurate information).
Nanotechnology, in the broadest sense, simply refers to technology that is engineered on the scale of nanometers (10^-9m).
When the federal government began offering grants to aid researchers and the study of nanotechnology, it immediately became necessary to develop a legal, and unambiguous, definition of the term. Now, nanotechnology is legally defined as the development of any system with at least one dimension measuring less than 100 nm (or 100 "billionths of a meter").
