What is nanotechnology?
Nanotechnology is the general words to all work in the field of advanced technology with nanoscale refers. Usually mean Nanvabady scale is around 1nm to 100nm. (1 nanometer is a Mylyardym meters).
The first spark nanotechnology (although at the time still had not known the name) was struck in 1959. This year with a speech by Richard Feynman as "a lot of space there are low levels of" brought the idea of nanotechnology. He offered this theory in the near future can the molecules and atoms as we direct manipulation.
Term nanotechnology Nvryvtayngvchy first time by Professor University of Tokyo in 1974 to the current language. He described the term for construction materials (equipment) that Tlvrans exact dimensions of them is nm, could use. In 1986, when the term by Eric Dkslr book entitled: "Creation Engine: Nanotechnology started» Recreation and this was defined. He formed the word deeper in the doctoral thesis and later studied it in the book entitled "How to Nanvsystmha molecular machines and their calculations" developed.


 

: the art of manipulating materials on an atomic or molecular scale especially to build microscopic devices (as robots).

 

Nanotechnology - technology based on the manipulation of individual atoms and molecules to build structures to complex, atomic specifications

 

 

definition at the physics portal:
Nanotechnology Definition: The development and use of devices that have a size of only a few nanometres. Research has been carried out into very small components, which depend on electronic effects and may involve movement of a countable number of electrons in their action. Such devices would act faster than larger components. Considerable interest has been shown in the production of structures on a molecular level by suitable sequences of chemical reactions. It is also possible to manipulate individual atoms on surfaces using a variant of the atomic force microscope.

 

 

A field of science whose goal is to control individual atoms and molecules to create computer chips and other devices that are thousands of times smaller than current technologies permit. Current manufacturing processes use lithography to imprint circuits on semiconductor materials. While lithography has improved dramatically over the last two decades -- to the point where some manufacturing plants can produce circuits smaller than one micron (1,000 nanometers) -- it still deals with aggregates of millions of atoms. It is widely believed that lithography is quickly approaching its physical limits. To continue reducing the size of semiconductors, new technologies that juggle individual atoms will be necessary. This is the realm of nanotechnology.Although research in this field dates back to Richard P. Feynman's classic talk in 1959, the term nanotechnology was first coined by K. Eric Drexler in 1986 in the book Engines of Creation.In the popular press, the term nanotechnology is sometimes used to refer to any sub-micron process, including lithography. Because of this, many scientists are beginning to use the term molecular nanotechnology when talking about true nanotechnology at the molecular level.

 

 

 

 

definition: Nanotechnology, or, as it is sometimes called, molecular manufacturing, is a branch of engineering that deals with the design and manufacture of extremely small electronic circuits and mechanical devices built at the molecular level of matter. The Institute of Nanotechnology in the U.K. expresses it as "science and technology where dimensions and tolerances in the range of 0.1 nanometer (nm) to 100 nm play a critical role." Nanotechnology is often discussed together with micro-electromechanical systems (MEMS), a subject that usually includes nanotechnology but may also include technologies higher than the molecular level.

What is Nanotechnology?
While many definitions for nanotechnology exist, the NNI calls it "nanotechnology" only if it involves all of the following:

1. Research and technology development at the atomic, molecular or macromolecular levels, in the length scale of approximately 1 - 100 nanometer range.

2. Creating and using structures, devices and systems that have novel properties and functions because of their small and/or intermediate size.

3. Ability to control or manipulate on the atomic scale

 

 

 

 

 

 

 

 

 

In fact, application of nanotechnology application will rooted basic elements. Each of these basic elements, special features that use them in different fields, will cause interesting properties. For example, the applications of nanoparticles can be targeted to Darvrsany simple, self-sufficient from renewable Bandazhhay detect cancer cells early and harmless, and analysis of pollutants in the environment. Also, carbon nanotubes with various applications that are in the following can be mentioned:
   • The exact biological imaging
   • chemical and biological sensors with a reliable and long life
   • identify and isolate specific DNA completely
   • Zhndrmany through gene transfer into cells is done by nanotubes.
   
• destroy bacteria
These are the only cases where the applications are too high for the basic elements are conceivable. Application of these basic elements in various industries, another tree called the tree industry "is given by referring to the study group Yndhandyshy, part tree industry, you can see it.
Finally, "Nanotechnology tree" that nanotechnology is introduced in the form of a chain approach to building basic elements of their application, in a four-level tree displays.
Referring to the study group Yndhandyshy, part tree technology, you can see it.
