Nano
The nanoscale is about a thousand times smaller than micro that is, about 1/80,000 of the diameter of a human hair. Approximately 3 to 6 atoms can fit inside of a nanometer, depending on the atom. Nano means ten to the minus ninth power (10-9), or one billionth.
Nanoscale technologies use the devices of only a few nanometres. Single molecules and atoms can be manipulated by nanotechnologists.
