3. MEANING OF NANO
TECHNOLOGY
Nanotechnology is the design,
characterization, production, and
application of structures, devices, and
systems by controlled manipulation of size
shape at the nanometer scale that
produces structures, devices, and systems
with at least one novel/superior
characteristics or prpoperty.

4. DEFINITION OF NANO
TECNOLOGY
According to Karen
Bresalu “Once the
province of science fiction,
nanotecnology,the
science of assembling
materials one atom at a
time , is now the rage
among silicon valley
investors.”

5. PIONEERS OF NANO
TECNOLOGY
 Richard
Feynman
Father of Nano
technology
 Norio taniguchi
Firs t coined the Term
Nano tecnology

6. HISTORY OF NANO
TECHNOLOGY
• The first ever concept was presented in 1959 by
the famous professor of physics Dr.Richard
Feynman .
• Invention of the scanning tunneling microscope
in 1981 and the discovery of fullerene(C60) in
1985 lead to the emergence of nanotecnology .
• The term “Nano-technology” had been coined by
norio

7. • The early 2000s also saw the
begnings of commercial
application of nanotecnology,
although these were limited to
bulk application of nanomaterials.
• Silver nano platform for using
silver_ nanoparticles as an
antibacterial agent ,
nanoparticle – based transparent
Sunscreens, and carbon nanotubes
for stain- resistant textiles.

electricity generated by
windmills.
• Increase storage of solar cells.

16. NANO TECHNOLOGY IN FASHION
• Nano-textiles is an emerging and interesting
application of nanotechnology. It involves dealing
with nano fibers at the atomic and molecular levels in
order to tweak their properties. This novel technology
can give rise to incredible clothing such as water-
resistant and dirt-free clothes, odor-less socks, and
intelligent clothes that can perfom climate control for
you
• Various uses of nano technology in fashion are:-
• Cosmetics: Titanium dioxide – UV protective.
• Silver nanoparticles -
• Skin care – vitamins deeper into the skin.
• Armour dress – nanodress.
• Clothes that react automatically to the
environment.
• Garments water – and stain – repellennt or
wrinkle – free.
• Carbon nanoparticle.

17. NANOTECHNOLOGY IN AGRICULTURE
• Research has shown nanoparticles to be a
groundbreaking tool for tackling many arising
global issues, the agricultural industry being no
exception. In general, a nanoparticle is
defined as any particle where one
characteristic dimension is 100nm or less.
• Various uses of nano technology in
agriculture are:-
• Growth of plant harmone.
• Increase yeild and fertilization.
• Agriculture waste products in
production of graphine.
• Carbon nanotube - identify and kills
pathogens.
• Nano manipulation of seeds.

22. POSSIBILITIES FOR THE FUTURE OF
NANO TECHNOLOGY
• Nanotechnology may make it possible to manufacture
lighter, stronger, and programmable materials that ▫
require less energy to produce than conventional
material ▫ and that promise greater fuel efficiency in
land transportation, ships, aircraft, and space vehicles.
• The future of nanotechnology could very well include
the use of nanorobotics.
• 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

23. • There would be an entire nano surgical field to help
cure everything from natural aging to diabetes to
bone spurs.
• There would be almost nothing that couldn’t be
repaired (eventually) with the introduction of nano
surgery.

24. • Nano-particles can get into the body through the skin,
lungs and digestive system, thus creating free radicals
that can cause cell damage.
• Once nano-particles are in the bloodstream, they
will be able to cross the blood-brain barrier.
• The most dangerous Nano-application use for
military purposes is the Nano-bomb that contain
engineered self multiplying deadly viruses that can
continue to wipe out a community, country or even a
civilization.
• Nanobots because of their replicating behavior can
be big threat for GRAY GOO
