Nanotechnology is a little known
science, that deals with building things
out of atoms and molecules. This issimilar to how nature works, building
things at the molecular level

IntroductionIntroduction
Nanotechnology deals with experimentationwith objects that have dimensions of less thanabout 1,000 nanometers. This is incrediblesmall. A nanometer is one billionth of a meter insize.
Nanotechnology involves the control of
materials at the nano-scale,achievingminiaturization through atomic and molecularmanufacturing techniques.

Defination of NanotechnologyDefination of Nanotechnology
It is "nanotechnology" only if it involves all of the
following:
1. Research and technology development at the atomic,
molecular or macromolecular levels, in the length scale ofapproximately 1 - 100 nanometer range.
2. Creating and using structures, devices and systems that
have novel properties and functions because of their small
and/or intermediate size.
3. Ability to control or manipulate on the atomic scale.

There are two more concepts commonly
associated with nanotechnology:
Positional assembly
to get the right molecular parts in the right
places
Self replication
to keep the costs down

Introduction to MEMSIntroduction to MEMS Micro-Electro-Mechanical Systems (MEMS) is the
integration of mechanical elements, sensors, actuators, and
electronics on a common silicon substrate through
microfabrication technology.
MEMS promises to revolutionize nearly every product
category by bringing together silicon-basedmicroelectronics with micromachining technology,
making possible the realization of complete systems-on-a-
chip.

The Advantage ofThe Advantage of
NanotechnologyNanotechnology The Nano-products could be programmed to
manipulate the molecules and atoms after they
have been made. Creation of computer chips.
Fleets of medical nanorobots smaller than a cell
could roam our bodies eliminating bacteria,clearing out clogged arteries, and reversing the
ravages of old age.

Disadvantages ofDisadvantages of
NanotechnologyNanotechnology who would control a technology as powerful
as this promises to be?
Change that is too rapid could upset
economies and create disruption instead of
construction.
Destructive Nanomachnies could do immense
damage to unprotected people and objects.

ConclusionConclusion
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 everyone can reap its
benefits; a technology so fundamental that it will
radically change our economic and politicalsystems; a technology so imminent that most of us
will see its impact within our lifetimes. Such is the
promise of Nanotechnology.
