Nanotechnology a brief guide
This is a complete basic and short guide about Nanotechnology i.e. what it means, what it will do, its applications, its uses, its future, disadvantages and almost everything. I make it little bit eye catchy and funnier by adding relative graphics and pictures so you can never get bored. At the end you found it 1000 times more interesting and funnier. Enjoy my work world.

Transcripts - Nanotechnology a brief guide
• Nano means “extremely small”. When quantifiable
it translate to one-billionth , as in the
• Technology is
the making, usage,
and knowledge of
in order to solve
a problem or
perform a specific function.
What is Nanotechnology ?
• Nanotechnology is the study of the
controlling of the matter.
• It involves developing
materials, devices or
possessing at least
within that size.
• Nanotechnology deals with structures sized
between 1 to 100 nanometers.
• The first ever concept was presented in 1959
by the famous professor of physics
Dr. Richard P.Feynman.
• Invention of the scanning
tunneling microscope in 1981 and
the discovery of fullerene(C60) in
1985 lead to the emergence of nanotechnology.
• The term “Nano-technology" had been coined
by Norio Taniguchi in 1974.
• The early 2000s also saw
the beginnings of
commercial applications of
these were limited to bulk
• Silver nano platform for
as an antibacterial agent
and carbon nanotubes for
What can Nanotechnology
• It helps to clean the environment.
• Nanotechnology has the
potential to increase the
efficiency of energy
• Nanotechnology will solves major health
• Nanotechnology will be smaller, cheaper
lighter yet more functional.
• It requires less energy
and fewer raw materials

Manufacturing techniques of
1. Bottom up:
In the bottom up approach
different materials and
devices are constructed
from molecular components
of their own. They
themselves by recognizing
the molecules of their own
• Examples of molecular
self assembly are Watson
crick base pairing , nano-
2. Top down:
• In top down approach
nano objects and
materials are created
by larger entities
without bouncing its
usually top down
approach is practiced
less as compared to
the bottom up
• Solid-state techniques
can also be used to
create devices known
systems or NEMS,
which are related to
systems or MEMS.
•Mechanisms and structures are miniaturized
to nanometric scale.
• Fullerene are a family of carbon allotropes named
after Buckminster Fuller.
• They are molecules composed entirely of carbon, in
the form of a hollow sphere, ellipsoid, or tube.
• Spherical fullerenes are called buckyballs.
• Cylindrical fullerenes are called
• Recently discovered is the
"buckyegg", by researchers at
• Carbon nanotubes are allotropes of carbon
with a cylindrical nanostructure.
• Nanotubes are members of
the fullerene structural
• Their name is derived from
their long, hollow structure with the walls
formed by one-atom thick sheets of
carbon, called Graphene.
Properties of Carbon
• Highest strength to weight ratio, helps in
creating light weight spacecrafts.
• Easily penetrate membranes such as cell walls.
Helps in cancer treatment.
• Electrical resistance changes significantly when
other molecules attach themselves to the carbon
atoms. Helps in developing sensors that can
detect chemical vapours.
• They have length to diameter ratio upto
Some of it’s Applications
• Replacing transistors from the silicon chips as
they are small and emits less heat.

• Nanorods are one morphology of
• They may be synthesized from metals
or semiconducting materials.
• A combinations of ligands act as shape control
agents and bond to different facets of the
nanorod with different strengths. This allows
different faces of the nanorod to grow at
different rates, producing an elongated object.
• It’s dimensions range from 1-100 nm.
Uses of Nanorods
• In display technologies,
because the reflectivity
of the rods can be
changed by changing
their orientation with
an applied electric field.
• It is used in micro-electro-mechanical systems
• In cancer therapeutics.
• A nanobot is a microscopic robot built with
• Nanobots are self
It also has some degree of autonomy and can
• Capable of replication
• Since nanobots would be microscopic in size, it
would probably be necessary for very large
numbers of them to work together to perform
microscopic and macroscopic tasks.
Applications of Nanobots
• Nanobots is used to go inside the body and
make a bionic eye, fix broken leg, blood clot.
• Nanobots will allow us to live longer than
normal like 50 years.
• Nanobots are used in the detection of toxic
components in environment.
• Nanobots are used in cancer

developed by Nokia Research Centre(NRC)
and the University of Cambridge(UK).
• The Morph will be super

itself from available light
sources using photovoltaic nanowire grass
covering it’s surface.
