I think that we need to define Nanotechnology or Nanoscience for ourselves and use this term with our definition until the larger community comes up with a more popular and/or understood definition.
When I speak of Nanotech to friends, the usual reply is the question, what is it? I like the following definition: "Nanotechnology, a material science, is the manipulation of matter on a nanoscale." *

Having defined Nanotechnology, we can then go on to define nanoscale: particles ranging in size from .1 to 100 nanometers.

If we can get the world community to accept our definition, we can either rest on our laurals or we can go on to conquer the world.
