2. Nanotechnology
Revolutionarily Very Big (Small)Thing

3. THROUGH THE SLIDES
 What Is NanoTechnology?
 History Of NanoTechnology
 Synthesis of Nano materials
 Classification of Nano materials
 Applications Of NanoTechnology
 Advantages And DisadvantagesOf
Nanotechnology
Future of Nanotechnology

4. What Is
Nanotechnology?

5. What Is Nanotechnology?
•Nanotechnology is defined as
the study and use of structures
between 1 nanometer and 100
nanometers in size.
•Nanotechnology (“nanotech”)
is manipulation of matter on
an atomic, molecular and supra
molecular scale

7. Example: Human Hair, Approx. 1x105 nm
HOW SMALL IS NANOSCALE ?
A Nanometer is
one billionth of a
meter

8. Nano materials - Synthesis

9. Nano material - Classification

10. Is
Nanotechnology
to be
cared ?

11. SHOULD WE CARE ABOUT
NANOTECHNOLOGY ?
WeAll ShouldCare !
Becauseit can bring
revolution in the current
industrialization and
manufacturing processes.

12. VARIOUS FIELDS OF NANOTECHNOLOGY

13. Electronics:
• Nano Transistors
• Nano Diodes
• OLED(Organic Light EmittingDiode)
APPLICATIONS OF NANOTECHNOLOGY

14. Energy:
• Batteries
• FuelCells
• SolarCells
APPLICATIONS OF NANOTECHNOLOGY

15. ADVANTAGES

16. MATERIAL
With NT,we cancreate unique
materials and products whichare:
• Stronger
• Lighter
• Durable
• Precise

17. • Computers can become abillion
times faster and a million times
smaller
• Automatic Pollution Cleanup
INDUSTRIAL

18. MEDICAL
• Endof Illnesses (i.e. cancer, heart
disease)
• Universal Immunity (i.e. aids,flu)
• Body Sculpting
(i.e. change your appearance)

19. DISADVANTAGES

20. DISADVANTAGES
 Lossof jobs (in manufacturing,
farming, etc)
Carbon Nanotubes could cause
infection of lungs
Atomic weapons could be more
accessible and destructive

22. FEW EXAMPLES FOR FUTURE
USE OF NANOTECHNOLOGY
 ELECTRONIC PAPER
NOKIA MORPH
CONTACT LENS
