The 'nano' in 'nanotechnology' is often thought of as a shortened form of 'nanometer‘, which is one billionth (10-9) of a meter. The diameter of one human hair is about 10,000 to 80,000 nanometers.
Any Unit of Measure
However, theoretically, it can be used to refer to one billionth of any measure of interest--for example, a nanosecond refers to one billionth of a second.
nanometer
nanosecond
nanogram
nanomole
What Does ‘Technology' Mean?
TECHNOLOGY: (from the American Heritage Dictionary, 4th Edition, 2000)
1 a. The application of science, especially to industrial or commercial objectives.
b. The scientific method and material used to achieve a commercial or industrial objective.
2. Electronic or digital products and systems considered as a group: a store specializing in office technology.
3. Anthropology. The body of knowledge available to a society that is of use in fashioning implements, practicing manual arts and skills, and extracting or collecting materials.
How does it differ from 'science'?
While the notion of 'science' has often been contrasted with that of 'technology'--the first referring to the building of theory and the second referring to the application of this theory--such a distinction may be blurred in the case of nanoscience and nanotechnology.
