Nanotechnology, a brand new technology for studying the laws of motion and properties within electrons, atoms and molecules in the scale of 0.1-100 nanometers.
Scientists, in the process of studying the composition of matter, have found that a few, dozens of countable atoms or molecules isolated at the nanometer scale significantly exhibit many new properties, and the technology that utilizes these properties to create devices with specific functions is called nanotechnology.
Nanoscience and technology is a science and technology based on many modern advanced science and technology, which is the product of the combination of modern science (chaos physics, quantum mechanics, mesoscopic physics, molecular biology) and modern technology (computer technology, microelectronics and scanning tunneling microscope technology, nuclear analysis technology).
Nanoscience and technology, in turn, will lead to a series of new science and technology, such as: nanophysics, nanobiology, nanochemistry, nanoelectronics, nanoprocessing technology and nanometrology.

The main difference between nanotechnology and microelectronics
Nanotechnology studies the control of individual atoms and molecules to achieve the specific function of the device, which works by using the fluctuation of electrons; whereas microelectronics mainly realizes its function by controlling the population of electrons, which works by using the electron's particle nature to work. The purpose of people's research and development of nanotechnology is to realize the effective control of the whole microscopic world.
Nanotechnology is a highly cross-cutting and comprehensive discipline, and the research involves a wide range of modern science and technology.In 1993, the International Steering Committee for Nanotechnology divided nanotechnology into six subdisciplines: nanoelectronics, nanophysics, nanochemistry, nanobiology, nanoprocessing and nanometrology.
In which nanophysics and nanochemistry are the theoretical basis of nanotechnology, while nanoelectronics is the most important element of nanotechnology.
