Nanotechnology now represents no lessthan the next industrial revolution
Nanotechnology is the understanding and control ofmatter at dimensions of roughly 1 to 100 nanometers,where unique phenomena enable novel applications
Anything is nanotechnology that, under therubric of nanotechnology, makes money.
