Question

nanotechnology Nanotechnology is now seen as contributing to numerous environmental solutions, from cleaning up hazardous waste sites to producing strong but lightweight materials for auto bodies. ˌnænoʊˌtɛkˈnɑləˌʤi

Accepted Answer

The science of manipulating materials on an atomic or molecular scale, especially to build microscopic devices such as robots. Nanotechnology, or nanotech for short, deals with matter at a level that most of us find hard to imagine, since it involves objects with dimensions of 100 billionths of a meter (1/800th of the thickness of a human hair) or less. The chemical and physical properties of materials often change greatly at this scale. Nanotechnology is already being used in automobile tires, land-mine detectors, and computer disk drives. Nanomedicine is a particularly exciting field: Imagine particles the size of a blood cell that could be released into the bloodstream to form into tiny robots and attack cancer cells, or “machines” the size of a molecule that could actually repair the damaged interiors of individual cells.
