Definitions of nanotechnology on the Web:

* Technology development at the atomic, molecular, or macromolecular range of approximately 1-100 nanometers to create and use structures, devices, and systems that have novel properties.
plan2005.cancer.gov/glossary.html

* Nanoscience and nanotechnology involve studying and working with matter on an ultra-small scale. One nanometre is one-millionth of a millimetre and a single human hair is around 80,000 nanometres in width.

* A branch of science and engineering devoted to the design and production of extremely small electronic devices and circuits built from individual atoms and molecules.

* a manufacturing technology able to inexpensively fabricate most structures consistent with natural law, and to do so with molecular precision. [FS]

* A technology that creates small materials at the scale of molecules by manipulating single atoms. The name nano comes from the size of molecules which is measured in nanometers - or one billionth of a meter (0.000000001 meter). The dimension of single atoms is ten fold smaller. ...

* A precise molecule by molecule control of products and byproducts in the development of functional structures.

* The science and art of making devices that are smaller in scale than MEMS, often at a molecular size, generally fabricated by chemical processes that result in the growth or formation of certain useful structures

* The science and technology of building electronic circuits and devices from single atoms and molecules.

* incorporates scientific advances in protein synthesis, molecular engineering and micro-computing. It is creating a set of tools and processes that will enable the synthesis of materials and structures at the atomic level.5

* Technology on the nanometer scale. The original definition is technology that is built from single atoms and which depends on individual atoms for function. An example is an enzyme. If you mutate the enzyme's gene, the modified enzyme may or may not function. In contrast, if you remove a few atoms from a hammer, it still will work just as well. ...

* Technology dealing with matter on a molecular size scale of nanometers (1 billionth of a meter).
fpmicro.com/resources/glossary.htm

* first coined by K. Eric Drexler in 1986, in the book Engines of Creation, the term refers to the manipulation of matter on the scale of the nano-meter (one billionth of a meter). The goal of nanotechnology is to control individual atoms and molecules to create computer chips and other devices that are thousands of times smaller than current technologies permit. ...

Answer 2

A key understanding of nanotechnology is that it offers not just better products, but a vastly improved manufacturing process. A computer can make copies of data files—essentially as many copies as you want at little or no cost. It may be only a matter of time until the building of products becomes as cheap as the copying of files. That's the real meaning of nanotechnology, and why it is sometimes seen as "the next industrial revolution."

My own judgment is that the nanotechnology revolution has the potential to change America on a scale equal to, if not greater than, the computer revolution. — U.S. Senator Ron Wyden (D-Ore.)

Answer 3

Nanotechnology, the science of the small. Nano is Greek for dwarf, and nanoscience deals with the study of molecular and atomic particles, a world that is measured in nanometers (billionths of a meter or 10-9 ).

Nanotechnology research has focusly primarily on molecular manufacturing -- the creation of tools, materials, and machines that will eventually enable us "to snap together the fundamental building blocks of nature easily, inexpensively and in most of the ways permitted by the laws of physics." A leading nanotech scientist describes past efforts at molecular level manufacturing as attempts to assemble LEGO pieces while wearing boxing gloves. Nanotechnology, he believes, will enable us to take off the gloves and build extraordinary things.

Answer 4

Encyclopedia: Nanotechnology Source:Wikipedia
Nanotechnology comprises technological developments on the nanometer scale, usually 0.1 to 100 nm (1/1,000 µm, or 1/1,000,000 mm). The term has sometimes been applied to microscopic technology. Nanotechnology is any technology which exploits phenomena and structures that can ....

Answer 5

Nanotechnology is a field of applied science focused on the design, synthesis, characterization and application of materials and devices on the nanoscale. Nanotechnology is a sub classification of technology in colloidal science, biology, physics,chemistry and other scientific fields and involves the study of phenomena and manipulation of material at the nanoscale, in essence an extension of existing sciences into the nanoscale. Two main approaches are used in nanotechnology: one is a "bottom-up" approach where materials and devices are built up atom by atom, the other a "top-down" approach where they are synthesized or constructed by removing existing material from larger entities. A unique aspect of nanotechnology is the vastly increased ratio of surface area to volume present in many nanoscale materials, which opens new possibilities in surface-based science, such as catalysis. This catalytic activity also opens potential risks in their interaction with biomaterials.

Answer 6

Nanotechnology is the engineering of functional systems at the molecular scale.In its original sense, 'nanotechnology' refers to the projected ability to construct items from the bottom up, using techniques and tools being developed today to make complete, high performance products.

Answer 7

Any fabrication technology in which
objects are designed and built by the specification and
placement of individual atoms or molecules or where at least
one dimension is on a scale of nanometers.

The first unequivocal nanofabrication experiments took place
in 1990, for example with the deposition of individual xenon
atoms on a nickel substrate to spell the logo of a certain
very large computer company.

Nanotechnology has been a hot topic in the hacker subculture
ever since the term was coined by K. Eric Drexler in his book
"Engines of Creation", where he predicted that nanotechnology
could give rise to replicating assemblers, permitting an
exponential growth of productivity and personal wealth.

Answer 9

The page this information is on is built up from pixels. Imagine each of those pixels holding a book, each page could hold a library.. ;)

I did play about with pixels, and links to images to experiment with a computerized form of nanotechnology. I was playing because of 'invisibility' or what appears to be invisible. In my toying I could make a one pixel invisible and hold a image as big as I wanted-in 1 pixel

The information had to be there first, then resized but it did go invisible and yet still hold all the information I originally put in there. The original size too yet all in 1 pixel, some images were massive, in 1 pixel

I have provided a link to a blog I just created to show simulated nanotechnology on the computer
