what is NANOTECHNOLOGY???

BASIC IMFORMATION

Nanotechnology is the engineering of functional system 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 techniques and tools being developed today to make complete, high performance products.

WHAT IS MEANING OF NANOTECHNOLOGY???

NANOTECHNOLOGY, shortened to 'NANOTECH', is the study of the controlling of matter on an atomic and molecular scale. Generally nanotechnology deals with structure of the size 100 nanometers or smaller in at least one dimension, and involves developing materials or devices within that size. Nanotechnology is very diverse, ranging from extensions of conventional device physics to completely new approaches based upon molecular self-assembly, from developing new materials with dimensions on the nanoscale to investigating whether we can directly control matter on the atomic scale.

There has been much debate on the future implications of nanotechnology. Nanotechnology has the potential to create many new materials and devices with a vast range of applications, such as in medicine, electronics and energy production. On the other hand, nanotechnology raises many of the same issues as with any introduction of new technology, including concerns about the toxicity and environmental impact of nanomaterials, and their potential effects on global economics, as well as speculation about various doomsday scenarios. These concerns have led to a debate among advocacy groups and government on whether special regulation of nanotechnology is warranted.

Nanotechnology has the potential to change every part of our lives. Nanotechnology affects all materials: ceramics, metals, polymers, and biomaterials. New materials are the foundation of major technological advances. In the coming decade nanotechnology will have an enormous impact. Future advances could change our approaches to manufacturing, electronics, IT and communications technology making previous technology redundant and leading to applications which could not have been developed or even thought about, without this new approach.
