Nanotechnology (sometimes shortened to "nanotech") is the study of manipulating matter on an atomic and molecular scale. Generally, nanotechnology deals with developing materials, devices, or other structures possessing at least one dimension sized from 1 to 100 nanometres. Quantum mechanical effects are important at this quantum-realm scale. atomic molecularnanometresQuantum mechanicalquantum-realmatomic molecularnanometresQuantum mechanicalquantum-realm Nanotechnology (sometimes shortened to "nanotech") is the study of manipulating matter on an atomic and molecular scale.

A nanometre, marked with the symbol "nm", is a length equal to one billionth of a meter or a millionth of a millimetre. 1 nm = 10-9 m = 10-6 mm = 10-3 m A nm corresponds to a fragment of metal containing about 4 atoms. Classic under the microscope are visible particles sized more than nm. The prefix "nano" comes from the ancient Greek where it means "dwarf". In science and technology "nano" refers to units of measure, i.e. the one in a billion.

Nano-technologies implemented in practice: Some examples of nano-technologies that are already made and used in practice, even if they are still expensive (January 2009):  Lakes of cars with higher grades (resistant to scratches; autorefacere; with putting into service since 2003) rear-view  mirrors which do not auto men that  Windows does not condense water on ceiling transparent  Windows auto producing electric current; others that darkens after desire  improvement of material properties  adhesive substances (chemical products) which, subject to e.g. in microwave, allow smooth and peel off two pieces of metal

How nanotechnology will help MAN Nanitii will be used in medicine, it can be anticipated to diseased cells eventually.The problem of mankind will be on hand whose "scientist" would fall.

A molecular assembler A molecular assembler is a system proposed by the nano-machine, i.e. the nanometric level construction, combines reactive molecules via mecano-synthesis, building larger parts and precise atomic level. They, in turn, are assembled by other mechanisms to create very precise, macroscopic parts that could be used in building the infrastructure or technology (e.g. pipes, nets, lenses, etc.)

NanosensorsNanosensors Are any biological, chemical, or surgical sensory points used to convey information about nanoparticles to the macroscopic world. Their use mainly include various medicinal purposes and as gateways to building other nanoproducts, such as computer chips that work at the nanoscale and nanorobots. Presently, there are several ways proposed to make nanosensors, including top-down lithography, bottom-up assembly, and molecular self-assembly surgicalnanoparticles macroscopicnanorobots top-down lithography, bottom-up assembly molecular self-assemblysurgicalnanoparticles macroscopicnanorobots top-down lithography, bottom-up assembly molecular self-assembly

DNA nanostructures

The nanosensor is made up of "reporter" molecules, which reacts to cellular electrical activity. These molecules are attached to particles of gold, that can penetrate easily into cells. The result is a sensor that can be scanned using a laser to measure the electrical activity of the cell, indicating whether it is in a good condition.

A serious problem is that it is not only very few know about the impact of nanoparticle on the human body. Made some cosmetic testing showed that titanium dioxide nano scale does not penetrate through the skin. However tests have not been complete. Some animal studies have shown that nanoparticulele can be produced by inhalation lung damage. Development of nano-scale will entail as quickly and thorough study of the impact of these products for humans.
