Nanotechnology is extremely inter-disciplinary, comprises of physics, chemistry, biology, materials science, and the full variety of the engineering disciplines. The word nanotechnology is been used widely as shorthand to refer to both the technology of emerging field and science. Basically defined, nano-science comprises the basic understanding of physical, biological and chemical properties on atomic and near-atomic scales. Nanotechnology, barely defined, employs controlled manipulation of these atomic properties to make materials and as well other functional system with exclusive capabilities.

In the contrary to recent engineering hard work, nature developed “nanotechnologies” over billions of years, employing enzymes and catalysts to manage with beautiful accuracy various types of atoms and molecules into compound microscopic structures, which make life probable. These natural products are built with huge competence and have inspiring capabilities, like the power to yield solar energy, to change minerals and water into livelihood cells, to store and procedure huge amounts of data using great arrays of nerve cells, and to copy completely billions of bits of information stored in molecules of deoxyribonucleic acid (DNA).

Even more ground-breaking will be the manufacture of nanoscale machines and nanoscale devices for integration into micro- and macro scale systems. Once again, nature has led the way with the manufacture of both linear and rotary molecular motors. These biological machines perform such tasks as muscle contraction (in organisms array from clams to humans) and carrying little packets of material around within cells as being powered by the eco-friendly, energy-efficient fuel adenosine triphosphate. Scientists are only starting to grow the tools to make functioning systems at such small scales, with most proceeds based on electronic or magnetic date processing and other storage systems. The energy-efficient, reconfigurable, and as well self-repairing aspects of biological systems are now becoming understood.

The likely impact of nanotechnology processes, machines, and products is predictable to be extensive, affecting almost every imaginable information technology, energy source, farming product, medical device, pharmaceutical, and other material used in developed. In the meantime, the dimensions of electronic circuits on semiconductors carry on shrinking, with minimum characteristic sizes now reaching the nanorealm, under 100 nanometers. They are huge markets driven by the fast advance of information technology.
