Simply stated, it is theworld of the very smallthings, such as

molecules and atoms.A nanometer is onebillionth of a meter.

Nanotechnology deals with the study of Materials of size 10-9 m.

Nanotechnology is the fun and the easiest way to explore the science of

matters smallest particles.

The Nanotechnology is the branch of science & engineering that deals with

things smaller than 100 nanometers.

Nanotechnology creates and uses structures that have novel properties

because of their small size.

Nanotechnology is not just the science but it also touches the on a variety

of science such as physics, chemistry, mechanical engineering , microbiologyand so on.

Some definitions of nanotech also include a reference to molecular systems

and devices.

A nanometer-sized particle is

also smaller than a living cell

and can be seen only with the

most Powerful Microscopes

available today. A sheet of paper is about100000

nanometers thick. The width of a

human hair is approximately

80000 nanometers thick.

This is about one hundred

thousand times smaller than the

diameter of a human hair.

The word nanotechnology first appears in RichardFeynmannslecture Theres plenty of room at thebottom on December 29, 1959.

The term "nano-technology" had been coined in 1974by Norio Taniguichi to describe semiconductorprocesses involving control on the order of ananometer.

Researcher K. Eric Drexler was the first person to

popularize this technology in the early 1980s.

It will make our lives more secure , improvehealthcare delivery, and optimize our use of

limited resources.

SECURITY

Provides superior and lightweight materials.

Advanced computing.

Increased situational awareness.

Powerful monitions.

Information Technology

Memory storage: Electronic memory designs in the past havelargely relied on the formation of transistors.

Novel semiconductor devices

Displays

Quantum computers: Entirely new approaches for computingexploit the laws of quantum mechanics for novel quantumcomputers, which enable the use of fast quantum algorithms.

AdvantagesWith NT, we can

create uniquematerials and productswhichare:

Stronger

Lighter Cheaper Durable Precise

Computers can

become a billiontimes faster and amillion timessmaller

Automatic PollutionCleanup

Manufacturing atalmost no cost

End of Illnesses (i.e.

cancer, heartdisease)

Universal Immunity(i.e. aids, flu)

Body Sculpting(i.e. change yourappearance)

Industrial MedicalMaterial

Health and safety issues

Nanoparticles can cause seriousillness or damage human body.

Environmental issues Nanopollution is created by

toxic wastes from

nanomaterial manufacturing Enhances Global warming in

the long run Grey-goo

It is a hypothetical situationwhere self replicating

nanobots go out of control,and consume all matter onearth.

The Nanofactory

The ability to build

anything we can design,by manipulating

molecules under direct

computer control, will

be a joltto the system.
