INTRODUCTION Imagine chips embedded in the human
body reporting every body movement and just
waiting to strike at those nasty bacterial
invaders, clothing smart enough to monitor our
health and save us from environmental hazards
,huge building and machine having the capability
to repair and adjust themselves to the vagaries
of environment or a regular wrist watch doubling
up as super computer. Thanks to the
nanotechnology all of these wonders and many more
are possible.

PRINCIPLE Nanotechnology involves working with
matter at the scale of one billionth of a matter.
It refers to the manipulation of matter on the
minutest scale i.e. atoms and molecules. At the
nano scale ,the physical, chemical and biological
properties of materials differ in fundamental and
valuable ways from the properties of individual
atoms and molecules of bulk matter. Properties of
an electron inside matter and atomic interaction
are influenced by material variation on the
nanometer scale. It is even possible to control
fundamental properties of materials like their
melting temperature, magnetic properties, charge
capacity, and even their colors, without changing
the materials chemical composition.

APPLICATIONS OF
NANOTECHNOLOGY

• MEDICAL AREA
• SUPERCOMPUTING
• MEMS
• SMART CLOTHING

• MEDICAL AREA
• Nano surgical tools can help in making up the
  damages at molecular and cellular level.
• Nanotechnology may also be useful for
  developing ways to detect and eradicate cancer
  cells.
• Nanorobots could also be programmed to perform
  delicate surgeries or remove obstructions in the
  circulatory system.

NANO ROBOT OR NANOBOT
NANO ROBOTS ARE NANO MACHINES EMBEDDED IN OUR
BODY PERFORMING THEIR DUTIES AS DISCIPLINED
SOLDIERS . BEFORE BEING SENT INTO THE BODY ON
THEIR SEARCH ON DESTROY MISSION, THEY HAVE TO BE
PROGRAMMED WITH A SET OF CHARACTERSTICS THAT LET
THEM CLEARLY DISTINGUISH THEIR TARGETS FROM EVERY
THING ELSE .

SUPERCOMPUTERS Assemblers will enable the
construction of both molecular electronic and
molecular mechanical devices. It is to be
expected that electronic effects will permit
faster switching times than do mechanical
effects, permitting the construction of faster
and much powerful computers.

  10,000 TIMES THINNER
• THAN HUMAN HAIR.
• THESE CONSIST OF ROLLED UP SHEETS OF MULTI
  LAYER CARBON ATOMS IN HEXAGON SHAPE.
• THEY CONDUCT ELECTRICITY BETTER THAN COPPER AND
  ARE MORE STRONGER THAN STEEL WIRE .

MICRO ELECTRO-MECHANICAL SYSTEM (MEMS)
Micro-Electro-Mechanical Systems (MEMS) is the
integration of mechanical elements, sensors,
actuators, and electronics on a common silicon
substrate through micro fabrication technology.
While the electronics are fabricated using
integrated circuit (IC) process sequences (e.g.,
CMOS, Bipolar, or BICMOS processes), the
micromechanical components are fabricated using
compatible "micromachining" processes that
selectively etch away parts of the silicon wafer
or add new structural layers to form the
mechanical and electromechanical devices.

NANOTECHNOLOGY AND ENVIRONMENT

• Advances in nano science will lead to new means
  of
• Reducing the production of wastes
• Remediation of industrial contamination.
• Providing potable water
• Improving the efficiency of energy production and
  use.
• On the other hand, the introduction of large
  quantities of nano structured materials into our
  society may have unforeseen consequences for
  environmental quality.

• Advantages of Nanotechnology
• Nano-structuring is expected to bring about
  lighter, stronger and programmable materials.
• It is not impossible to have devices that can
  convert house hold waste into fresh food, diamond
  rings or antique works of art.
• In medical field we will have microscopic robots
  floating in our blood streams fighting against
  cancer cells, AIDS HIV virus, genetic disorders
  or even ageing.

28

• We can create pollution free environment by
  having automatic clean up systems of existing
  pollutants.
• Many extinct plants and animals can be studied
  and even reintroduced.
• Some of the novel inventions like airplanes,
  space crafts and other transport made from
  lightweight material are possible with nano
  techniques.
• Computers billions of times faster and with
  massive memory but with miniscale storage devices

29

• Disadvantages of Nanotechnology
• Nanotech particles will penetrate living cells
  and accumulate in animal organs,
  and can perhaps enter the food chain.
• There is no regulatory body dedicated to check
  this potent and powerful invasion
• Their impact on environment is unknown.e.g.
  Nanotubes of carbon use gallium arsenic and
  minute traces of gallium arsenide in the body
  could prove toxic.

30

• Changes in the proteins due to the presence of
  nano particles in the blood stream could trigger
  dangerous effects like blood clotting
• A whole new class of toxins or the environmental
  problems may be created due to nanotechnology.
• Reaction of humans and existing environment to
  these nanoparticles and nanobots and their
  acceptance is not known.

31
Nanotechnology with all its challenges and
opportunities will become a part of our future.
The researchers are optimistic for the products
based upon this technology. Nanotechnology is
slowly but steadily ushering in the new
industrial revolution.
