NANOTECHNOLOGY

ABSTRACT:

Nanotechnology and nanotechnology applications refers to a range of techniques used to manipulate matter at the scale of atoms and molecules. The word ‘Nano’ is a size scale, rather than a material, one nanometre being one billionth of a metre.

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 we can make computer chips. If we rearrange the atoms in dirt, water and air we can make potatoes.

The emerging field of nanoscience and nanotechnology is leading to a technological revolution in the new millennium. The application of nanotechnology has enormous potential to greatly influence the world in which we live. From consumer goods, electronics, computers, information and biotechnology, to aerospace defense, energy, environment,
and medicine, all sectors of the economy are to be profoundly impacted by nanotechnology.

Nanorobotics is the technology of creating machines or robots at or close to the scale of a nanometre (10-9 metres). As no nanorobots have so far been created, they remain a hypothetical concept at this time. Nanorobots are poised to bring the next revolution in technology and medicine, replacing the cumbersome and toxic Industrial Age and opening humankind up to incredible possibilities.

This paper presents the concept of nanotechnology with referance to existing technology. It throw’s light on future scope of application of nanotechnology.

It is all about making big things in smaller ways !

Introduction:

What is NanoTechnology?
Nanotechnology involves development of materials (and even complete systems) at the atomic, molecular, or macromolecular levels in the dimension range of approximately 1-500 nanometers.It is the manipulation of matter on a near-atomic scale to produce new structures, materials, and devices. This technology has the ability to transform many industries and to be applied in many ways to areas ranging from medicine to manufacturing.
