What is nanotechnology
A BASIC DEFINITION:-nanotechnology is a engineering of functional systems at the molecular scale. This cover both current work & concepts that are more advanced.
In its original sense nanotechnology refer to the projected ability to construct items from the bottom up, using techniques & tools being developed today to make complete, high performance products
Meaning of nanotechnology
When K. Eric Drexler (right) popularized the word'nanotechnology'in the 1980's, he was talking about building machines on the scale of molecules, a few nanometerswide—motors, robot arms, and even whole computers, far smaller than a cell. Drexler spent the next ten years describing and analyzing these incredible devices, and responding to accusations of science fiction. Meanwhile, mundane technology was developing the ability to build simple structures on a molecular scale. As nanotechnology became an accepted concept, the meaning of the word shifted to encompass the simpler kinds of nanometer-scale technology. The U.S. National Nanotechnology Initiative was created to fund this kind of nanotech: their definition includes anything smaller than 100 nanometers with novel properties.
