Nanotechnology is the manipulation of matter with at least one dimension sized from 1 to 100 nanometers (nm). At this scale, commonly known as the nanoscale , surface area and quantum mechanical effects become important in describing properties of matter.
The nanometre (international spelling as used by the International Bureau of Weights and Measures; SI symbol: nm), or nanometer (American spelling), is a unit of length in the International System of Units (SI), equal to one billionth (short scale) or one thousand million (long scale) of a meter (0.000000001 m) and to 1000 picometres.
Control of the critical dimensions are the most important factors in nanotechnology. Nanometrology today, is to a large extent based on the development in semiconductor technology. Nanometrology is the science of measurement at the nanoscale level. Nanometer or nm is equivalent to 10^-9 m.
Nanoelectronics – use of nanotechnology on electronic components, including transistors so small that inter-atomic interactions and quantum mechanical properties need to be studied extensively. Nanomechanics – branch of nanoscience studying fundamental mechanical (elastic, thermal and kinetic) properties of physical systems at the nanometer ...
Nanomaterials describe, in principle, chemical substances or materials of which a single unit is sized (in at least one dimension) between 1 and 100 nm (the usual definition of nanoscale [1]). Nanomaterials research takes a materials science -based approach to nanotechnology , leveraging advances in materials metrology and synthesis which have ...
A nanoparticle or ultrafine particle is a particle of matter 1 to 100 nanometres (nm) in diameter. [1] [2] The term is sometimes used for larger particles, up to 500 nm, or fibers and tubes that are less than 100 nm in only two directions. [2]: 394 At the lowest range, metal particles smaller than 1 nm are usually called atom clusters instead.

Nano (symbol n) is a unit prefix meaning one billionth.Used primarily with the metric system, this prefix denotes a factor of 10 −9 or 0.000 000 001.It is frequently encountered in science and electronics for prefixing units of time and length.
