“Nanotechnology is the art and science of

manipulating matter at the nanoscale”

A nanometer is…– one billionth of a meter

Human Hair: Approx. 1x105 nmDNA Sample: Approx. 2 nm

Because it can bring revolution in the current

industrialization and manufacturing processes.

• CNT’s are the alloptropes of carbon with a cylindrical nanostructure.

• These have been constructed with length to diameter ratio upto 28,000,000:1.

• APPLICATIONS:-

2. To make bullet proof clothes.

3. In electric circuits.

4. In solar cells.

5. In paper batteries.

6. In NRAM (nano RAM).

RECENT DEVELOPMENT :2. In may2005, a sensor

is developed to detect different compounds in air.

3. In 2007, a radio receiver consisting of a single nanotube is demonstrated.

RECENT DEVELOPMENT :

3. In 2008, it is shown that a sheet of nanotubes can operate as a loud -speaker if alternanting current is applied.

– Universal Immunity (i.e. aids, flu)

– Body Sculpting (i.e. change your appearance)

– Loss of jobs (in manufacturing, farming, etc)

– Carbon Nanotubes could cause infection of lungs

– Oil & Diamonds could become worthless

– Atomic weapons could be more accessible and destructive

Examples of Future Use of NT
