Introduction:
Imagine a technology so powerful that it
will allow such feats as desktop
manufacturing, cellular repair, artificial
intelligence, inexpensive space travel,
clean and abundant energy and
environmental restoration; a technology
so portable that every one can reap
What is nanotechnology?
Nanotechnology is molecular
manufacturing or, more simply building things
one atom or molecule at a time with
programmed nanoscopic robot arms. A
nanometer is one billionth of a meter (3 to 4
atoms wide). Utilizing the well-understood
chemical properties of atoms and molecules
(how they stick together) a nanotechnology
proposes the construction of novel molecular
devices possessing extraordinary properties.
The trick is to manipulate atoms individually
and place them exactly where needed to
produce the desired structure.
Concepts of nano technolgy:
There are two concepts commonly
associated with nanotechnology:
· Positional Assembly
· Self-Replication
Clearly, we would be happy with any
method that simultaneously achieved the
following three objectives. However, this
seems difficult without using some form of
positional assembly (to get the right
molecular parts in the right places) and some
form of self-replication (to keep the costs
down).
1. Get essentially every atom in the right
place.
2. Make almost any structure consistent with
the laws of physics and chemistry that we
can specify in atomic detail.
3. Have manufacturing costs not greatly
exceeding the cost of the required raw
materials and energy.
Nano mechanical computational systems:
The positioning systems in molecular
assemblers need devices to direct their
programmed movements and ways to store
these programs. Computers and control
systems similar to those already devised for
macroscale robotic arms can be
implemented at the molecular level. At the
current rate of development, molecular
electronic computers that would be used for
this purpose will likely be commercialized
well before the robot arms.
Nanotechnology, a break through in all fields:
Nanotechnology has been successful in
almost all the fields irrespective of its kind and
with the help of this technology it is possible
to perform any type of operations starting from
manipulating the molecules for separating
impurities to the stage where it is the easy
method for the production of power.
