5. Prevention of diseases:
–Creation of
antimicrobial coatings -
silver nanoparticle
coatings on their
refrigerators allows
them to keep food
fresher and kill
bacteria thus
6. CONT…….
• Nanotechnology is able to
make materials on a small
scale.
• Nanomask is capable of
filtering particles up to 0.3
microns.
• That is sufficient to block
viruses.
• Viruses are smaller thus are
more affected by the Brownian
motion, making them more
likely to hit the filters.
7. • Coating of
important
arteries with a
material
(Thaxton's
nanoparticles)
to smoothen the
walls of the
arteries to
prevent
cholesterol from
8. • A layer of nanostructures
(Titanium Dioxide) could be
added to the bone.
–Improves the bone hardness
–Carbon nanotubes can be
placed in between bones to
speed up recovery
9. Dendrimers
• Based on nanoscale particles
– Dendrimers
• The coat the cell to prevent HIV
viruses from entering
• Are able to do so as they are
smaller than the virus itself
10. Not many people go for frequent checkups
– Once a year or once every
two years
– Nano Sensors
• Placed in the bodies
• Monitor the condition of the
body in real time
• Detect diseases in early

13. Generating less pollution during the manufacture of materials
• silver nanoclusters - as
catalyst can significantly
reduce the polluting
byproducts generated in the
processorganic chemicals polluting groundwater.
Cleaning up
used to manufacture
propylene oxide.
The iron nanoparticles
disperse throughout the
body of water and
decompose the organic
16. Electronic Chips:
• Chips tend to overheat due to
increase in processing speed in
the chip
• Carbon nanotubes can help to
decrease temperature of the
chip
18. uses
- used as a needle at a molecular level
– Injecting liquids into cells
– Cells remains unharmed
– Used by Fujitsu to make heatsinks
– Semiconductor wiring material
– zinc oxide nano-particles will become the best
sunblock in the market
– Help humans transmit nerve signals
– May provide a cure for cancer as they kill
cancerous cells and allow noncancerous cells to
live.
19. Agriculture
• Benefits: higher crop yields, reduction in the
use of pesticides and improved water
management
• Applications and Uses: nanoparticles for
removing contamination, moisture
sensors, detection of pathogens
Cosmetics
• Benefits: UV protection, enhanced delivery of
medicated skin products
• Applications: clear sunscreens, beauty care
products, Cosmeceuticals, Nutraceuticals .

23. • The future of nanotechnology could very well
include the use of
• These nanorobots have the potential to take
on human tasks as well as tasks that humans
could never complete.
• The rebuilding of the depleted ozone layer
could potentially be able to be performed.
24. • The future of nanotechnology
rests in the hands of the
current scientists that are
ready and able to help guide
this very young science into the
next realm
• Much of the funding for nano—
research may very well
require something amazing in
order to continue. The funding
