The world is shrinking into a global village as the horizon of technology is a hybrid expand.It field of applied science and technology. Nanotechnology focuses on manipulating atoms individually and place them in a pattern to produce a desired structure. These are various areas which various branches colloidal science, applied physics, materials science, supramolecular chemistry, device physics and electrical and mechanical engineering, even. Nanotechnology uses two main approaches, known approaches from the top down and bottom.

In the ?top down?, the nano-objects are assembled from larger molecular objects at the atomic level without control. In the ?bottom up? approach, materials and devices are built from molecular components which constructs chemically by principles of molecular recognition. Instances of nanotechnology in recent use is the production of polymers based on molecular structure and design of the development of computer chips based on surface science. When the nanotechnology is implemented in the image analysis software, some teams are able to study the body language of the consumer and, with exact timing, precisely, one can understand the position of a person, impatience and the diversity of expressions as facial frown, smile or frown.

Human skin has the ability to transmit electrical signals that can be used as a transmission method, researchers were able to develop equipment designed with nano sensors that have the uncanny ability to ?see? and ?hear? people use them in reality. Nanotechnology could facilitate the manufacture of the new generation of computer components with massive storage capacity. In the field of IT, there is something called Moore?s Law that says, in simple terms, the processing power of the computer chip base grew exponentially at a height greater than all eighteen months from the beginning.

The evolution of computers clearly shows us that mechanical computing tradition was not completely abandoned. In 1990, engineers at the University of Minnesota, has produced an entire family of micromechanical digital logic devices, including electrostatically actuated linear sliding micron logic elements limited to a mechanical one-dimensional track, suitable for low speed radiation hard digital works in a hostile environment for electronic devices to function. Perhaps the best characterized nano-mechanical design is logical Drexler rod that is not well built so far. In this model, a sliding rod with a knob interconnects at first a second rod sliding knob at right angles. On the basis of the location of the first rod, it may be able to move or not move. The contact block is the basis for logical operations.

There has been much research goes into this for the good of humanity. In the press meet to Journal of Applied Sciences Hewlett-Packard said its scientists have invented an alternative to eventually replace transistors in computers. This was demonstrated by their Quantum Science Research group. They invented a ?crossbar latch,? which provides the signal restoration and inversion required for general computing without the need for transistors.
