presentation on nanotechnology.

2. NANO TECHNOLOGY
THE SCIENCE OF THE SMALL

3. What is Nanotechnology ?
• Let’s take a look at the Dictionary :
• Nanotechnology is the branch of science that deals with
dimensions & tolerances of less than 100 nanometers, esp. the
manipulation of individual atoms & molecules.
• The Book ‘The Next Big Thing Is – Small’ defines it as, the
art of manipulating & rearranging individual atoms & molecules
to create useful materials, devices & systems.
• In simple words, the design & engineering of things at
the Nanoscale.

4. Nanoscale
refers to
structures
which are
between 1
to 100
nanometers
in scale.

5. Nanoscale ?
• A Nanoscale refers to structures which are between 1 to
100 nanometers in scale.
• While a millimeter is one 1/1000 part of a meter.
• A Nanometer is 1/1000000000 (one billionth) part of a
meter.
A single hair from our head is 60,000 nanometers
PIN
wide. HAIR
• One nanometer is about 6 atoms.
• A pin is about 1mm across the head, which equals to 10
lakh nanometers.
• A human red blood cell is 8,000 nanometer RED
PIN in scale. BLOOD
CELL
Thus it is a science of many small things.

6. For Example..
• Things that we often take
for granted can behave in
many different ways.
• You can understand the
differences if we talk about
Spherical cluster of carbon atoms

7. If we arrange carbon atoms in one way, we get
graphite.
[Like If we take the everyday pencil, it’s
Graphite which runs through the centre of the
pencil.
That’s Carbon.
If you arrange them other way,
get Diamonds.

8. Uses of Nanotechnology
Gold on a Nanoscale doesn’t look Gold at all, it’s either
red, blue, green depending on the size & shape of the
particles.

9. Gold Nanoparticles have also found a Range of
Applications which include improving the speed of
computers, to produce really intense paints, they have
also began to be used in the fight to treat cancer.

10. Another Uses of Nanotechnology
Another application of NanoTech can be seen in batteries by making
the Granules inside the battery at a nanometer scale it’s possible to
recharge it faster & the battery lasts longer.

12. NanoTech has a potential to
change the world in many
positive ways.
It will improve many products
that we use everyday & in making
new products possible.
Nanotechnology is still a very
young science but once is
starts advancing it will affect
almost every part of our life.

13. are working hard to make this tiny creature into a big
reality.
