Nanotechnology is the technology of building

devices, such as electronic circuits, from single atoms and

molecules. Nano means "small", of the order 10-9m, so

nanotechnology is (among other things) generally a conversation

about new science that creates machines the size of

molecules.

a technology executed on the scale of less than 100 nanometers, the

goal of which is to control individual atoms and molecules,

especially to create computer chips and other microscopic

devices.


Nanotechnology is a term for devices and chemicals engineered at

the nanometer scale. Broadly, it encompasses two separate

ideas:

"Molecular nanotechnology" is the assembly of structures to

complex, atomic specifications by means of mechanosynthesis.

"Nanoscale materials" encompasses any manipulation of matter at

lengths from 1 to 100 nm, but often includes things on the

micrometer scale.

Nanotechnology refers to the smallest scale of the engineering,

not necessarily the size of the finished product.

Nanotechnology (sometimes shortened to "

"line-height: 19.196428298950195px; background-color: rgb(255, 255, 255)">nanotech")

is the manipulation of matter on an atomic and molecular scale. The

earliest, widespread description of nanotechnology[1][2] referred

to the particular technological goal of precisely manipulating

atoms and molecules for fabrication of macroscale products, also

now referred to as molecular nanotechnology. A more generalized

description of nanotechnology was subsequently established by the

National Nanotechnology Initiative, which defines nanotechnology as

the manipulation of matter with at least one dimension sized from 1

to 100 nanometers. This definition reflects the fact that quantum

mechanical effects are important at this quantum-realm scale, and

so the definition shifted from a particular technological goal to a

research category inclusive of all types of research and

technologies that deal with the special properties of matter that

occur below the given size threshold. It is therefore common to see

the plural form "nanotechnologies" as well as "nanoscale

technologies" to refer to the broad range of research and

applications whose common trait is size. Because of the variety of

potential applications (including industrial and military),

governments have invested billions of dollars in nanotechnology

research.

(ref:wikipedia)

nano refers to something that is of the order 10-9. A nano-meter is

therefore a very small unit of length. Nano technology refers to

very small machines, small enough to work at a cellular or even

molecular level. Check out the SF story Blood Music by Greg

Bear.

Nanotechnology is the the branch of technology that deals with

dimensions and tolerances of less than 100 nanometers, esp. the

manipulation of individual atoms and molecules. (The definition

from my dictionary) In my words, Technologies that deal with how

things behave when they are very small. VERY small. A nanometer

(nm) is one BILLIONTH of a meter. Wow! One strand of hair is about

100,000 nm. For more information, vist
