What is nanotechnology?

Answer 1

As a common definition it is said that Nanotechnology is a field of applied science focused on the design, synthesis, characterization and application of materials and devices on the nanoscale.

For easy understanding let us try to understand it in a simpler definitions and explanations. Nanotechnology is the postulated ability to manufacture objects and structures with atomic precision, literally atom by atom. This would mirror the abilities of living cells, which do exactly the same thing, although based on evolution and not design.

This technology involves the very minute particles where products are manufactured by getting essentially every atom in the right place and making almost any structure consistent with the laws of physics specified in molecular detail.

To explain by an example: Manufactured products are made from atoms. The properties of those products depend on how those atoms are arranged. If we rearrange the atoms in coal we can make diamond. If we rearrange the atoms in sand (and add a few other trace elements) we can make computer chips. If we rearrange the atoms in dirt, water and air we can make potatoes.

Todays manufacturing methods are very crude at the molecular level -casting, grinding, milling of resources to manufacture a product. In the future, nanotechnology will be able to do the fundamental building blocks of nature easily, inexpensively and in most of the ways permitted by the laws of physics.

Correct arrangement of atoms...Sounds that easy, isn't it?♥

Answer 2

It's basically research in miniture.
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



Nanotechnology research has focusly primarily on molecular manufacturing -- the creation of tools, materials, and machines that will eventually enable us "to snap together the fundamental building blocks of nature easily, inexpensively and in most of the ways permitted by the laws of physics."
