“The nanoscale is defined as a linear scale of 1 to100 nanometers [= less than 10 to 1000 atoms].”
Nanotechnology…What is it?
“Nanotechnology incorporates all tools andtechniques which lead to the application of theproperties of matter at the nanoscale”.

The US Nanotechnology Initiative ….. the drivers?
1) The increasing maturity of Scanning Probe tools which couldimage, characterize and manipulate atoms
…a new paradigm “Bottoms-up manufacturing!”
2) The Semiconductor industry.Positive; Economic, scalable, complex, mass production.Negative: Pending physics constrains, loss of an industrial base.
3) A precedent, Date Storage Industry & Giant Magneto-resistance,from concept in 1987 to 100% industry adoption in 2004, market$ 40B
5) Political receptiveness for a new government technology program.
4) Confidence engendered by the discovery of theCarbon Nanotube, a new and man made material.
