- Nanotechnology is the creation and use of materials or devices at extremely small scales.
- These materials or devices fall in the range of 1 to 100 nanometers (nm).
- One nm is equal to one-billionth of a meter (.000000001 m), which is about 50,000 times smaller than the diameter of a human hair.
- Scientists refer to the dimensional range of 1 to 100 nm as the nanoscale, and materials at this scale are called nanocrystals or nanomaterials.

- The nanoscale is unique because nothing solid can be made any smaller.
- It is also unique because many of the mechanisms of the biological and physical world operate on length scales from 0.1 to 100 nm.
- At these dimensions materials exhibit different physical properties; thus scientists expect that many novel effects at the nanoscale will be discovered and used for breakthrough technologies.
