Why should you know something
about Nanotechnology?
The National Science Foundation
estimates that by the year 2015
there will be a need for 2 million
workers worldwide in the fields of
nanoscience and nanotechnology.
An additional 5 million
workers will be needed in
support areas for these fields.
By 2015, nanotechnology is
expected to be a $3 trillion
“industry”
What is a “nano”?
• A nano is one billionth of a meter or 10-9
m
• A normal person can walk 32 kilometers or
about 20 miles in one day. If a person
were shrunk so that they were one
nanometer tall, how long would it take
them to walk the length of a dollar bill?
• 24 years
What is Nanotechnology?
• The science of manipulating atoms and molecules to
make new materials and devices.
• Interdisciplinary – where science and engineering
interconnect
• Occurs at the 1-100 nanometer range
– One nanometer is 10-9 meters or about 3 atoms long.
For comparison, a human hair is about 60-80,000
nanometers wide
Two Parts of Nanotechnology
• Nanotechnology is often divided into two parts:
– Nanoscience – where researchers learn about the chemical and
physical properties of materials at the 1- 100 nanometer (nm)
scale. Materials at 1-100 nm are called nanostructures. They are
the smallest things that can be made.
– Nanotechnology – where researchers develop and apply
materials at this scale to develop new products or methods; i.e.,
turning nanostructures into useable tools and applications
Unique Properties and
Nanotechnology
• Nanotechnology involves the manufacturing and application of
instruments and materials that have unique properties because of
their small size.
• At the nanoscale, properties of materials behave differently and are
said to behave under atomic and molecular rules.
• Researchers are using these unique properties of materials at this
small scale to create new and exciting tools and products in all
areas of science and engineering.
Nanofabrication
– Top-down nanofabrication – start with
large material and bring it down to the
nanoscale
– Bottom-up nanofabrication – start with
individual atoms and build upwards to
make a nanostructure
Nanoscience Biomimicry
Ways scientists are attempting to mimic the wonders of
nanoscience in nature:
•sticky “feet”
•strong spider silk
•self-cleaning light reflecting butterfly wings
•optical nanoscience
•water collecting beetle backs
•tough and light toucan beaks
•and the list could go on and on.

Nanotechnology is not New!
Gold nanoparticles in glass are reflected as red
Ancient stained-glass makers knew if they put finely ground gold or silver
in the glass they would get beautiful colors. They used nanosized gold and
silver particles. Optical properties change with the nanoscale.
What are some applications
of Nanotechnology?
