Nano-Technology
The Wave Of The Future
The Beginning

In a talk given in 1959,
Richard Feynman was
the first scientist to
suggest that devices and
materials could someday
be fabricated to atomic
specifications: "The
principles of physics, as
far as I can see, do not
speak against the
possibility of maneuvering
things atom by atom."
The Vision

Over thirty years ago,
20TH Century Fox
produce a film called
“Fantastic Voyage.” In
this film, a diplomat was
dying because of a bloodclot until scientist shrunk
a 30-foot long clot-busting
metal ship to the size of a
pin and sent straight into
the diplomat. This put the
public eye’s interest on
nanotechnology.
What is Nanotechnology?

Nanotechnology is a new
technology for creating
structures in the nano
range. A nanometer is a
billionth of a meter, that
is, about 1/80,000 of the
diameter of a human hair,
or 10 times the diameter
of a hydrogen atom.
Scientist are working to
control or manipulate on
the atomic scale.

Nanotechnology is also
used for creating and
using structures, devices
and systems that have
novel properties and
functions because of their
small and/or intermediate
size.
Advances for the Future

Nanotechnology is
expected to make most
new products lighter,
stronger, cleaner, less
expensive and more
precise. Nano-technology
will represent advances in
the field of biology,
chemistry, physics,
engineering, computer
science and
mathematics.

Nanotechnology will
increase physician’s
options for prevention,
diagnosis, and treatment
of cancer. The major
research objective is to
design, model, and
fabricate molecular
machines and devices
that could be used in the
medical field.
Dangers and Benefits of
Nanotechnology

Dangers:




It can lead to an arm race within nations
Easy to smuggle because of small sizes
Cheap duplication and manufacturing can lead to an
economic disruption
Benefits:



Cheaper greenhouses
Nano-meter scale can take 100% of bacteria out of
water
Cheaper computers
Today’s Nano-technology

Stain resistant clothes and mattresses

Better sunscreen lotions

Reinforced tennis Rackets

Burn and Wound dressings
Future Products

Devices that can:
Sense the environment
 Process information or convert energy from
one form to another


These products are produced by nanoscaled sensors which can detected
contaminates within the environment or
other biochemicals.
The Nano- Robot

The Nano-Robots would
recognize specific
antigens,
therefore targets only
unhealthy cells. Medical
Nanotechnology will
consists of accurate
administration of
chemotherapy through
blood cells and pumps
that are programmed to
administer drugs at given
times rather than
continuously.
Nano-Technology Regulators

On Nov. 9,2005 the International
Organization for Standardization (ISO)
Technical Committee 229 met in London

During the meeting they established three
groups: terminology and nomenclature;
metrology and characterization; and
health, safety and the environment
