Nanotechnology

“Nanotechnology” chiefly refers to the science and technological development, dealing with matter at its molecular or atomic state. The aim is to super-compress the computer systems that we use to the tiniest possible measurement. With smaller electronic gadgets debuting the market each day, the practical implementation of nanotechnology does not sound too theoretical.

Molecular Technology is implemented following three approaches:

Top-down approaches – This technique does not require development from he very basic stages but rather rearrangement of the molecular structure of complex structures to develop new complex structures.

Some technologies which had evolved from solid-state silicon methods, now utilize nanotehnology to manufacture microprocessors smaller than 100nm.

Nanoelectromechanical systems (NEMS) are manufactured utilizing the solid-state techniques.

Bottom-up approaches – By this method the smaller, simpler units of matter are arranged in order to form complex matter.

Nanotechnology in DNA science is used to construct well formed complex structures from nucleic acids and DNA. Here nanotechnology is applied on the basis of Watson-Creek base pairing.

Bottom-up approaches utilizes supramolecular chemistry and molecular recognition to develop the complex structures from the basic components like atom or molecule.

Functional approaches: Using this technique, the final structure is built without placing any special stress on the approach, be it bottom-up or Top-down method.
