2. Nano-technology
The word nano is from the Greek
word ‘Nanos’ meaning Dwarf. It is a
prefix used to describe "one billionth" of
something, or 0.000000001 mm
A prefix that means
very, very, small.
“Nanotechnology is
manufacturing with atoms”

3. Nanotechnology
Nanometre
Nano-

Nanobots
Nanotechnology
The art and science of making useful
particles that does particles on the
nanometer length scale.
Buckminster
fullerene
Carbon-60 buckyball is
shaped like a soccer ball.
Structure of Diamond
“Your nail can grow 1/2nm while reading this!”

4. Richard Feynman
Adventures of a Curious Character
By
Richard Feynman
“There’s Plenty of Room at
the Bottom”
Richard Feynman
introduces the world to
nanotechnology (1959 & 1984)
Nano-Proud
Nano-
American Physical Society meeting at the
California Institute of Technology (CalTech) on
December 29, 1959, long before the term
nanotechnology was explained by him.

5. Understanding Size:
 It’s not just how big
you are
 It’s what you can do
with it

6. What is a
nanoparticle?
One million nanoparticles placed
side by side would span 1mm.
GCSEScience
Chapter6
Nanoparticles are
small particles
which has size less
than 100nm

7. SYNTHESIS
We can produce
nano materials
using
Top Down process
Bottom Up process

8. Applications

9. Nanoparticle Applications
Electronic
 High performance and smaller components,
 High conductivity materials.
 e,g, capacitors for small consumer devices such as
mobile phones
Nano-Chips
Magnetic
•Increased density storage media.
•Nanomagnetic particles to create improved detail and
contrast in MRI images.
•Scanning probe microscope systems from Nano Science
instruments.

11. Nano particles in Solar cells
NANOPARTICLES
 Nano particles are used in production of Solar cells
 Nano particles used in solar panel are in size of
10 nm to 70 nm

12. Nano particles in Solar cells
Uses
 High energy density and more durable batteries.
 Electro catalysts for high efficiency fuel cells.
 Renewable energy, ultra high performance solar cells.
It give energy for long life .So, it is
Sustainable for Future Life

13. Nanotrees
 Nanotrees are very small trees which has size less
than 1 nm to 100 nm

14. Uses
 Nano trees use the Sun's Energy to convert Water
Into Hydrogen Fuel .
 It produce Hydrogen Fuel for low cost.
Uses of hydrogen fuel
 It produce enormous amount Energy
 It is more efficient

15. NANO MITES
It has many applications
Some of them are
o MEDICINE
o ARMY

16. Nano mites in medicine
 USES
 It is used deliver the medicine in the body.
 It can detect the tumour cells.
 It help improve the health of the body.

17. In futures may be:
 In future ,we can invent
nanomites (nanobots)
with the help of nano
technology which will use
in Army for destruction of
opponent army forces.

18. NANOTECHNOLOGY
IN FUTURE
The Nanotechnology will rule the WORLD
Since it is Sustainable for Future Life
