Nanotechnology is actually a technology that makes matter from individual atoms and molecules.
From the state of research so far, about nanotechnology is divided into three concepts. The first one, molecular nanotechnology, was proposed by Dr. Drexler, an American scientist, in his book "Machines of Creation" in 1986. According to this concept, a machine for combining molecules can be made practical, so that all kinds of molecules can be combined at will and any kind of molecular structure can be created. This concept of nanotechnology has not made significant progress.
The second concept positions nanotechnology as the limit of micromachining technology. That is, the technology of artificially forming nanometer-sized structures through nanometer-precision "machining". This nanoscale processing technology, but also make the semiconductor miniaturization is about to reach the limit. Theoretically, even if the existing technology continues to develop, it will eventually reach its limit. This is because if the line width of the circuit is reduced, the insulating film that makes up the circuit will be extremely thin, and this will destroy the insulation effect. In addition, there are problems such as heat generation and wobbling. To solve these problems, researchers are working on new types of nanotechnology.
The third concept was proposed from the biological point of view. Originally, organisms had nanoscale structures within cells and biofilms.
The so-called nanotechnology refers to a brand-new technology to study the laws of motion and properties within electrons, atoms and molecules in the scale of 0.1 to 100 nanometers. Scientists in the process of studying the composition of matter, found in the nanometer scale isolated a few, dozens of countable atoms or molecules, significantly show many new characteristics, and the use of these characteristics of the manufacture of equipment with specific functions of the technology, known as nanotechnology.
Nanotechnology is a highly cross-cutting and comprehensive discipline, and the research involves a wide range of modern science and technology.
Nanotechnology now includes such disciplines as nanobiology, nanoelectronics, nanomaterials, nanomechanics, and nanochemistry. From the micron technology including microelectronics to nanotechnology, mankind is increasingly deeper into the micro world, people understand, transform the level of the micro world to an unprecedented height. China's famous scientist Qian Xuesen has also pointed out that the nanometer around and below the nanometer structure is a focus of the next stage of scientific and technological development, will be a technological revolution, which will cause another industrial revolution in the 21st century.
While there is still a long way to go before the application stage, due to the extremely broad application prospects nurtured by nanotechnology, developed countries such as the United States, Japan and the United Kingdom have attached great importance to nanotechnology, and have formulated research programs to conduct related research
"Nano" is the English translation of nanometer, a term used to describe the structure of the nanometer, the structure of the nanometer, the structure of the nanometer. Nanometer" is the English translation of nanometer, a unit of measurement, is one billionth of a meter, equivalent to about 45 atoms strung up so long. Nanotechnology is a multidisciplinary science and technology that studies the interaction and movement of matter at the nanoscale (between 0.1nm and 100nm) and utilizes these laws in practical applications. Its basic meaning is to recognize and transform nature in the nanometer size range, and to create new matter by directly manipulating and arranging atoms and molecules.
Nanoscience and technology is a science and technology based on many modern advanced science and technology, it 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), and nano-science and technology will lead to a series of new science and technology, such as nano-electronics, nano-materials science, nanomaterial science, nanomechanics, etc. Nanoscience and technology is considered to be a high-tech at the turn of the century.

The third concept was developed from a biological point of view. Originally, living things had nanoscale structures within cells and biofilms.
The main aspects of nanotechnology are: nanomaterials; nanoelectronics; nanodynamics; nanobiology; and nanopharmaceutics.
Nanotechnology research approach (approaches): from the nanotechnology research scale range, the research of nanotechnology can be taken "from small to large" (bottom up) and "from large to small" (). top down" approach. The "top down" approach utilizes mechanical and etching techniques to create nanoscale structures. The "bottom up" approach applies atom by atom or molecule by molecule to create organic and inorganic structures. The terms "top down" or "bottom up" can be used to measure the level of nanotechnology development.
Nanoscience and technology extend the means and capabilities of human beings to understand and transform the material world to atoms and molecules. The ultimate goal is to create products with specific functionalities directly from the novel physical, chemical and biological properties of atoms, molecules and matter at the nanoscale. This could change the way almost all products are designed and manufactured, realizing a quantum leap in production methods. Nanotechnology will thus have a profound impact on human beings and even change people's way of thinking and living.
Nanotechnology
Nanometer is a unit of length equal to 1 billionth of a meter, that is, 1nm=0.000000001m, roughly equal to the diameter of four atoms. Nanotechnology is a technology that seeks to compose new substances and develop new applications within the nanometer scale. It involves the field between macro and micro, has a very attractive prospect. For example, carbon nanotubes is a layer of graphite or several layers of carbon atoms curled into a cage-like fiber, hollow inside, the external diameter of only a few to tens of nanometers, equivalent to one ten-thousandth of a hairline, the density of only one-sixth of steel, but the strength is 100 times that of steel, it is the ideal material for fabrics, such as bulletproof undershirts. It can also be used as a coating for the base plate of the picture tube to produce a thin, energy-efficient wall-mounted TV screen. Nanotechnology can be used to imprison electrons in a nanoparticle or a very fine short wire, which can be made into a single electronic device, i.e., a single electron to control the circuit. The capacity and speed of computers could then be greatly increased. So-called quantum disks made with nanotechnology can make high-density magnetic recordings, storing 30,000 copies of the Dream of the Red Chamber per square centimeter of area.
Nanotechnology, information technology and biotechnology are known as the three leading technologies of the 21st century. The development of nanotechnology will have a great impact on material science, life science and medicine. In the material world of the micro and macro two fields, mankind has made great progress, and between them 1-100 nanometers in the world, scientists have found some physical and chemical phenomena, such as the object's strength, toughness, specific heat, electrical conductivity, diffusivity, magnetization rate, etc. is completely different from our existing common sense, by these brand new discovery may be The result of these new discoveries may lead to the introduction of new theories will give mankind often come to a significant impact, will become a continuous revolution.
Nanotechnology is a wonderful opportunity for the Chinese people in the process of scientific and technological development. At present, western countries such as the United States, Japan, the European Union have put forward their own nanotechnology development strategies and plans, China's business community and scientists work closely together to promote the continuous development of nanoscience.
