Abstract
Nanotechnology is defined as the production of devices with atomic or molecular level accuracy. Devices with a minimum feature size of less than 100 nanometers (nm) are considered to be products of nanotechnology. A nanometer is one-billionth of a meter (10-9 m) and is a unit of length, which is usually the most appropriate for describing the size of individual molecules.

Nanoscale notes hazy border between classical and quantum mechanics worlds; Thus, the implementation of nanotechnology promises to bring revolutionary possibilities. Production of nanomachines, nanoelectronics and nanodevices others undoubtedly will solve a lot of problems facing mankind today.

Nanotechnology is currently in a very infantile stage. Nevertheless, we now have the opportunity to organize the matter at the atomic level, and already there are many products available, as a direct result of our rapidly growing manufacturing capacity and function characteristics of size less than 100 nm. Mirrors that do not fog, biomimetic paint with a contact angle of about 180 °, gene chips, and fat-soluble vitamins in aqueous beverages are among the first manifestations of nanotechnology. Nevertheless, immenant breakthroughs in the field of computer science and medicine is where the real potential of nanotechnology will be reached first.

Nanoscience is an interdisciplinary field that aims to achieve a mature nanotechnology. By focusing on the nanoscale the intersection of the fields of physics, biology, engineering, chemistry, computer science and more, nanoscience is rapidly expanding. Nanotechnology centers popping up around the world as more funding is provided and increased market share nanotechnology. Rapid progress is manifested in the increase in the appearance of the prefix "nano" in scientific journals and news. Thus, as we increase our ability to manufacture computer chips with smaller features and improve our ability to cure the disease at the molecular level, nanotechnology here.

History of nanotechnology
The amount of space available to us for storing information (or for any other purpose) is enormous. As was first described in a lecture entitled "There's a lot of room at the bottom" in 1959 by Richard P. Feynman, there is nothing but our awkward size that keeps us from the use of this space. At one time it was not possible for us to manipulate single atoms or molecules, because they were too small for our instruments. Thus, it
it was entirely theoretical and seemingly fantastic. He described how the laws of physics do not limit our ability to manipulate individual atoms and molecules. Instead, it was our lack of appropriate methods to do so. However, he correctly predicted that the time would come in which atomically precise manipulation of matter inevitably come.

Professor Feynman described this atomic-scale production of a bottom-up approach, not a top-down approach, which we are accustomed. Currently, top-down method for manufacturing includes the construction of parts using techniques such as cutting, carving and molding.

Extremely small, strong and elastic components ...

• Smart materials

• Super materials

• Bucky tubes

• Nanogear

• nanometer

Nanomachines could also be incorporated into a variety of materials to make these materials react to their environment, or external commands. Examples of such materials are "smart" tissues that respond to the environment, becoming warmer or colder, and the furniture or walls which can be moved or change shape on command. Nanomachines could also be used as tools in the industry, and consumers. Such tools could be cut or glued material much more effectively than any large-scale, which is used today. Nanomachines can also repaired cars, furniture, appliances with, or almost anything else quickly and efficiently. Or, these objects can be developed nanomachines repair themselves should the need arise. Life would be greatly simplified by freeing people from the need to repair the objects at home or at work.

Smart Material: -
Makeup is one of the many multi-billion dollar industries that will benefit from a new class of coating called "the Smart Materials". This smart cover, of course, gender cross because, some utilitarian properties not associated with fashion. The proposed class of smart coatings, although very thin, the bag containing the capture nano composite structural materials. Laced with nano-computers, their extraordinary powers offer customs can still be imagined. As with all smart materials, conversion varnish on a flat screen color monitor or video phone is easy. Polish can be a desirable place to find your personal computer interface. Environmental monitoring can be switched on to warn of a high concentration of carbon dioxide, or radiation. One other physiological condition can be continuously monitored. All of these functions could run on solar power generated under normal lighting conditions.

Super Materials: -
Atomic precision design can produce metal structures, devoid of micro defects, greatly increasing the strength. Bearings made (unheard of) atomic precision (each atom in the "round") will take much longer to run cooler and carry heavy loads. Modern industrial products will be very useful, but why the first wave of industrialization diamondoid materials at the super composite materials are available? Nano materials can be constructed of material utility, that the scientific notation for mathematics. In the form of diamond, carbon 50 to 70 times stronger than steel and less than one quarter of the weight. Most of the carbon needed for the construction of a now available from the billions of pounds of fossil fuel burned in the atmosphere since the industrial revolution. Raw material supplies itself.

Bucky tubes -
The gears of the large components Buckytubes nanomachine ... Buckytubes carbon graphite sheets rolled into a tube (appears as a wire mesh tube) and "like" carbon in its diamond form, but with all available bonding strength are aligned along one axis of the diamond These tubes stronger fibers, and, perhaps, the strongest fiber cloth, so we start with the real racehorses material. Globus and design teams are chemically stable, and a variety of very rigid geometry, including gears, made of "nested" Buckytubes or baths within the tubes. This mechanism will be more rigid and is suitable for the "long" driveshaft. And talk about performance.
