  Nanotechnology - Wikipedia, the free encyclopedia
Nanotechnology is a sub classification of technology in colloidal science, biology, physics, chemistry and other scientific fields and involves the study of phenomena and manipulation of material at the nanoscale, in essence an extension of existing sciences into the nanoscale.
A unique aspect of nanotechnology is the vastly increased ratio of surface area to volume present in many nanoscale materials, which opens new possibilities in surface-based science, such as catalysis.
Nanotechnology and nanoscience got started in the early 1980s with two major developments; the birth of cluster science and the invention of the scanning tunneling microscope (STM).

 Nanotechnology: The Size of Things to Come
Nanotechnology deals with the creation and use of materials or devices at the level of molecules and atoms that are 1/1000th the width of a human hair--too small to be seen with a conventional laboratory microscope.
Nanotechnology allows scientists to work on the scale of molecules to create, explore, and manipulate the biological and material worlds measured in nanometers, one-billionth of a meter.
Some of the challenges anticipated by nanotechnology include the uncertain reaction of nanostructures within the body, and those devices or systems that may be so small that the body clears them too soon to be effective in detecting or imaging.

 Nanotechnology   (Site not responding. Last check: 2007-09-20)
Molecular nanotechnology is the ability to build objects to atomically exact specifications; to synthesize complex structures by using precise, mechanically controlled positioning of individual chemical building blocks.
Real nanotechnology, in the form originally envisioned, should not be confused with the modern misuse of the term to denote nanoscale bulk manufacturing - technologies operating on a scale of tens or hundreds of nanometers which do not involve atomic-scale precision or the exact specification of molecular structures.
Nanotechnology may or may not be the final technology, and the future may or may not lie in countless diamond specks.
