Nanotechnology is a new way of building and utilizing materials that are on an extremely tiny size scale, the scale of individual atoms and molecules. The fabrication of such small structures has proven to be quite challenging, however new methods are constantly emerging. Nanomaterials are interesting to scientists and engineers because they often have unusual and unique properties that are only possible due to their size.
Nanotechnology is a broad term that categorizes any type of research that is done on the nanoscale size. Although nanotechnology is most often associated with electronics, this is only one of many applications. There is nanotechnology research being done in many other fields of science and engineering.
