Reading your post, I agree with your premise of presentation.
However, there was an old comedy movie once that said in a fake ad
(imagine your radio advertiser's voice here):
"Now you can own this super ball made from the same material used in
tires of the B52 strategic bomber that safeguards our country. It is
simply amazing. You throw it down, it bounces up. You throw it up,
and it comes back down. All under its own power. No batteries
needed. Amazing"
That's how the "nano ads" sound to me now. Anyway they can fit it in,
they will.
But in one strict sense, simply rendering the particulates to size
could include them in a valid definition of "nanotech" nomenclature.
This was one of the earliest attempts to define the technology and its
output I could find. This dates to the 80s, although the nano/concept
has been around since the 50s.
************************
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.
Much of the work being done today that carries the name
'nanotechnology' is not nanotechnology in the original meaning of the
word. Nanotechnology, in its traditional sense, means building things
from the bottom up, with atomic precision. This theoretical capability
was envisioned as early as 1959 by the renowned physicist Richard
Feynman.
*************************
You can see the shift in meaning. Now it seems to used for pretty
much anything on a microscopic level. But in fact on almost all
accounts rendered by the scientific community, "nanoXXX" is regarded
as a reference point on an atomic level if not at least the molecular
level.
That being said, (and back to woodworking!) I am waiting to see if any
of these nano products make it to market soon. I have read about
paint that will block cell phone calls for about 5 years now. Never
seen it in use. Sure would be nice at the movies, eh? I have read
tales of sign companies that can power ad signs and change their
messages and colors with nanobots. There were claims of nano
technology breakthroughs that could block certain wavelengths of
radiation, and UV rays as well while remaining transparent.
It could be interesting days ahead for the coatings industry. Just
wish they would speed it up!
The rest of the applications for that technology in medicine, farming,
computing (remember the gel drives?), and on and on is just
staggering. Real nanotechnology will touch every part of our lives
very soon.
