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.
