Nano-technology
The word nano is from the Greek word ‘Nanos’ meaning Dwarf. It is a
prefix used to describe "one billionth" of
something, or 0.000000001 mm
A prefix that means very, very, small.

American Physical Society meeting at the California Institute of Technology (CalTech) on
December 29, 1959, long before the term nanotechnology was explained by him.
Understanding Size:
It’s not just how big you are
It’s what you can do with it
What is a
nanoparticle?
One million nanoparticles placed
side by side would span 1mm.

Nanoparticles are small particles which has size less than 100nm
SYNTHESIS
We can produce nano materials using
Top Down process
Bottom Up process
Applications
Nanoparticle ApplicationsElectronic High performance and smaller components, High conductivity materials. e,g, capacitors for small consumer devices such as
mobile phones
Nano-Chips
Magnetic •Increased density storage media.•Nanomagnetic particles to create improved detail and contrast in MRI images.•Scanning probe microscope systems from Nano Science instruments.

In Present…
Nano particles in Solar cells
NANOPARTICLES
Nano particles are used in production of Solar cells
Nano particles used in solar panel are in size of 10 nm to 70 nm
Nano particles in Solar cells
Uses
High energy density and more durable batteries.
Electro catalysts for high efficiency fuel cells.
Renewable energy, ultra high performance solar cells.
It give energy for long life .So, it is
Sustainable for Future Life
Nanotrees
Nanotrees are very small trees which has size less
than 1 nm to 100 nm
Uses Nano trees use the Sun's Energy to convert Water
Into Hydrogen Fuel . It produce Hydrogen Fuel for low cost.
Uses of hydrogen fuel It produce enormous amount Energy It is more efficient
NANO MITESIt has many applications
Some of them are o MEDICINEo ARMY
Nano mites in medicine
USES
It is used deliver the medicine in the body.
It can detect the tumour cells.
It help improve the health of the body.
In futures may be:
In future ,we can invent nanomites (nanobots) with the help of nano technology which will use in Army for destruction of opponent army forces.
NANOTECHNOLOGY
IN FUTURE
The Nanotechnology will rule the WORLD
Since it is Sustainable for Future Life
