Nanotechnology

Nanotechnology is a group of emerging technologies in which the structure of matter is controlled at the nanometer scale, the scale of small numbers of atoms, to produce novel materials and devices that have useful and unique properties. Some of these technologies impose only limited control of structure at the nanometer scale, but they are already in use, producing useful products. They are also being further developed to produce even more sophisticated products in which the structure of matter is more precisely controlled. The Foresight Nanotechnology Challenges focus on applying these developing technologies to solving important world problems.
it is the creation of functional materials, devices and systems through control of matter at the scale of 1-100 nanometers, and the exploitation of novel properties and phenomena at the same scale; nanotechnology is also called molecular manufacturing. Nanotechnology is a result of the combination of different scientific fields such as physics, biology, engineering chemistry, and computer science in addition to many more. The foundation of nanotechnology is that atoms make up all things in our world; which can be manipulated to produce almost anything.

It is the development of atoms in a certain object. Nanotechnology has become very popular in the past few years. It is a way to rebuild the systems of life. To make systems move faster than ever before. Nanometer is about 10 times the size of an atom. Each of these has a huge effect on a system. Still there are questions out there that keep people wondering how important nanotechnology is to us. Many wonder how will it affect them and if we should continue this researchNanotechnology is defined as “the development and use of devices that have a size of only a few nanometers. Research has been carried out into very small components many of which depend on quantum effect and many involve movement of very small number of electrons in their action. Such devices would act faster than larger components.

It is an anticipated manufacturing technology giving thorough, inexpensive control of the structure of matter. The term has sometimes been used to refer to any technique able to work at a submicron scale
Molecular manufacturing will enable the construction of giga-ops computers smaller than a cubic micron; cell repair machines; personal manufacturing and recycling appliances; and much more.
A basic definition: Nanotechnology is the engineering of functional systems at the molecular scale. This covers both current work and concepts that are more advanced.

In its original sense, 'nanotechnology' refers to the projected ability to construct items from the bottom up, using techniques and tools being developed today to make complete, high performance products.
