Did you know?

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.
