3. Electronic applications
• Displays(OLED,FED) with nano wires
as electrode would be of thickness
0.5mm
• Used in NED {Nano emitting diodes}
which has d brightness of 500 normal
LED’s
• These are also used in Laser Diodes
• They are used in glass fibres
• Used in filters in order to block the
IR rays
• Used in optical switches
• Data memory (MRAM,GMRHD)

4. Construction Applications
• Nano technology has the potential to
make construction cheaper,faster,easier
n safer
• Nano coatings are done for protection
against heat insulation ,fire ,and
corrosion
• Nano silica and clinker used to increase
densification and hence mechanical
properties and durability of
cementations materials.
• Used as building materials for wood,

5. Information Technology
• The storage capacity of the disk can
be improved dramatically
• Nanoparticles are used for
information storage
• Nano dimensional “photonic crystals”
are used in chemical/optical
computers
• “Quantum electronic devices” have
started replacing bulky conventional
devices

6. • Nano crystalline Zinc selenide,Zinc
Sulphide,Cadmium Sulphide and
lead telluride synthesized by sol-gel
techniques are candidates for nxt5
generation of light emitting
phosphors
• CNT’s are being investigated for low
voltage field emission displays. their
strength sharpness,conductivityand
inertness make tem potentially
efficient and long lasting emitter

7. Medicine Applications
• Controlled Drug delivery is possible using
Nano technology. Diffusion of medicine
through nanao pores polymer reservoir as per
the requirement is very useful in
controlling the disease
• Nanostructured ceramics readily interact
with bone and hence finds application as an
implant material
• Biosensitive nano particles are used for
tagging of “DNA and DNA chips”
• Used as agents in cancer therapy
• Nano crystalline zirconium oxide used as
“alternative materials for
implants”

8. Diet Applications
• Bacteria identification n food
quality identification using
biosensors
• Intelligent, active and smart food
packaging systems are few examples
of emerging of Nano technology
• Nano tech can be applied in the
production, processing n safety and
packaging of food

9. Textiles
• Use of Nano fibres makes the clothes
stain repellent nd wrinkle free
• Nano technology has been used to
integrate tiny carbon particle
membranes nd garautnee full surface
protection from the electro static
charges for the wearer

10. Cosmetics
• Used in Sunscreens
• Used in lipsticks
• Used in Skin Creams
• Used in Tooth Paste

11. Household
• The most prominent application of
nano technology in household is
“easy to clean” surfaces on
ceramics,glass,windows,floor
• It has improved the smoothness heat
resistance of the common household
equipment iron

12. Optics
• For optics nano technology also offers
scratch resistant surface coatings
based on nanocomposites
• It could allow for d precision of pupil
repair and other laser eye surgery

13. Chemical Industry
• Chemical catalysis and filtration
techniques are two places where nano
technology play a very vital role
• Used as fillers for paint systems
• Used in coating system based on nano
composites
• Used in impregnation of papers
• Used in switchable adhesives
• Used in Magnetic fluids

14. Engineering
• Used as wear protection for tools and
machines
• Used as anti blocking coatings,
scratch resistant coatings on plastic
parts etc.,
• It is used to manufacture lubricant
free bearings

15. Automotive Industry
• Used in light weight construction
• Used in tyres as fillers
• Used in sensors
• Used as coatings for windscreen and
car bodies
• Used in paintings(fillers ,basecoat,
clearcoat)

16. Energy
• Used in Fuel Cells
• Used in Solar cells
• Used in batteries
• Used in Capacitors
