NANOTECHNOLOGY IN

ELECTRONICS

Currently available microprocessors use

resolutions as small as 32 nm Houses up to a billion transistors in a single

chip

NANOCHIP

NANOELECTROMECHANICAL SYSTEM

(NEMS) SENSORS NEMS technology enables creation of ultra small

and highly sensitive sensors for various

applications

The NEMS force sensor shown in the figure is

applicable in pathogenic bacteria detectionA NEMS BACTERIA SENSOR

NANOTECHNOLOGY IN

CONSUMER PRODUCTS SUNSCREEN: Many sunscreens contain

nanoparticles of zinc oxide or titaniumoxide.

SELF-CLEANING GLASS

uses nanoparticles to make the glassphotocatalytic and hydrophilic.

TEXTILES:

coating fabrics with a thin layer of zincoxide nanoparticles,

SWIMMING POOL CLEANERS ANDDISINFECTANTS:

The oil particles adhere to bacteria,making the delivery of the bactericidemore efficient and effective

LPDS:

Quick Response Liquid PowderDisplay, a flexible digital screen, usingnanotechnology.

FUTURE OF

NANOTECHNOLOGY The buckyball (C60) has

opened up a excellent field of chemistry and material sciencewith many exciting applications

because of its ability to acceptelectrons.

New solar cells are based on

nanoparticles of semiconductors, nanofilms andnanotubes by embedding in acharge transfer medium.

Nanotechnology offers to

produce, magneto resistiveand anti-collision

automobile sensors.

Nanotechnology is viewed

as a key technology for thedevelopment of ultra light

materials

CONCLUSION

Even though nanotechnology has many applications it

has some risks behind it

If we inhale nano-particles at the manufacturing stage

will posses health threats The detailed study should be made on particular

nanomaterials before using it

Industries & government are conscious of this and

taking necessary steps in finding out nanoparticles that

causing hazards to the environment and how to make it

harmless

If processed in safe manner, no doubt nanotechnology

will bring benefits to the society
