The document discusses several applications of nanotechnology. It begins by summarizing some natural structures like spider silk and butterfly wings that demonstrate nanoscale properties like strength and iridescence. It then defines nanotechnology as the manipulation of matter between 1-100 nanometers. Some potential applications of nanotechnology mentioned include carbon nanotubes that are stronger than steel, graphene that is lighter than steel, and aerogels that are 98% air. The document also notes how nanotechnology can be developed using top-down or bottom-up approaches and lists some impacts like longer-lasting clothes, faster-healing bandages, and smoke-degrading lamps.

3. SPIDER WEB
The tensile strength of spider silk
is greater than the same
weight of steel and has much
greater elasticity.
Its microstructure is under investigation for
potential applications in industry, including
bullet-proof vests and artificial tendons.

4. Self-cleaning and superhydrophobic

5. BUTTERFLY WING
Various iridescent colors by thin-film interference: similar, analogous
structures made of keratin are found in iridescent bird plumage.

6. Gecko Foot
Gecko toes have special adaptations that allow them to adhere to most
surfaces without the use of liquids or surface tension.
The setae of a typical mature 70 g (2.5 oz) gecko would be capable of supporting a
weight of 133 kg (293 lb)

7. BONE
High compressive strength of about 170 MPa
(1800 kgf/cm²)
Lightweight yet strong and hard, and serve multiple functions.

8. NANOTECHNOLOGY
DETECTED!!!

9. Smaller size
Bigger Effect !!!
NANOTECHNOLOGY

10. Nanotechnology ???
Nanotechnology ???
Small ??? Big ???
Make the thing smaller ??? 10-9 ???

12. National Nanotechnology Initiative,
which defines nanotechnology as the manipulation
of matter with at least one dimension sized from
1 to 100 nanometers

14. Why usual size and nano size has
different properties??

15. quantum size effect
Quantum Size Effect
This effect does not come into play by going from macro to micro dimensions.
However, quantum effects can become significant when the nanometer
size range is reached, typically at distances of 100 nanometers or less.

16. Additionally, a number of physical (mechanical, electrical, optical, etc.)
properties change when compared to macroscopic systems.
One example is the increase in surface area to volume ratio altering
mechanical, thermal and catalytic properties of materials.
Impact
Photocatalyst, anti-bacterial, super-hydrophobicity,
self-cleaning properties, etc

Bottom Up

25. Top Down
These seek to create smaller devices by using larger ones to direct their
assembly.
High Energy Milling
Giant magnetoresistance
nanoelectromechanical systems
Focused ion beams

26. Bottom Up
These seek to arrange smaller components
into more complex assemblies.
Sol gel
Dip pen nanolithography

27. NANOTECHNOLOGY Impact!!!

28. Trousers and socks have been infused with
nanotechnology so that they will last longer
and keep people cool in the summer.

29. Bandages are being infused with silver
nanoparticles to heal cuts faster.
