1(No Transcript)
2What is Nanotech
- A field of science whose goal is to control
individual atoms and molecules to create computer
chips and other devices that are thousands of
times smaller than current technologies permit - For example A nanometer is one thousandth the
diameter of a human hair!

3Early applications
- Stain Glass
- Nanosized particles often have different
properties such as a change in color.
- Gold and silver nanosize impurities affect the
color of the glass.
- Medieval stain glass makers did not know they
happened upon nanoparticles.
4Early Theorist of Nanotech
- James Clerk Maxwell
- (1867) Envisioned first nanomachine that could
trap atoms while they move in a specific
direction, know as Maxwells Demon.
5Richard Feynman
- A well-known physicist
- Theorized building machines to manufacture at
atomic levels
- Predicted information could be stored at great
density at atomic levels
6Norio Taniguchi
- Tokyo professor
- In 1974 coined the term nano-technology in a
paper On the basic concept of Nano-technology
7Eric Drexler
- In late 1970s, began to invent molecular
manufacturing
- Understood molecular machines could manufacture
complex chemical products
- Introduced the term nano-technology
8Historical BreakthroughsBuckyBalls
- Discovered in 1985 by 3 scientists, Harry Kroto,
Richard Smalley and Robert Curl.
- A Buckyball is a highly stable sphere of 60
carbon atoms arranged into hexagons or pentagon
shapes.
- Buckyballs are important due to their high
superconductivity with electricity, and ability
to trap other atoms inside.
9Historical BreakthroughsAtomic Force Microscope
- Invented by Gerg Binnig and Cristoph Gerber at
IBM in 1986.
- AFM reads an objects surface with a needle so
sharp, its tip is a single atom.
- The outcome is a 3-D image up to 1,000,000x
magnification.
10Historical BreakthroughsCarbon Nanotubes
- Discovered by Sumio Iijima in 1991.
- Carbon nanotubes behave like metals or
semiconductors.
- Can conduct electricity better than copper,
transfer heat better than diamonds, and are among
the strongest materials known to man.
11Historical BreakthroughsDip-Pen Nanolithography
- Invented by Chad A. Mirkin in 1999.
- Combined with an Atomic Microscope, allows the
user to lay down or write with various
substances onto a surface at the nanometer
dimensions. - This can lead to smaller, more light weight, and
more reliable electronic devices.
12Current Situation
- Currently Nanotechnology is mostly in Research
and development stage
- 2000 Expenses for RD was 825 Million, IN 2005
it was 4.1 Billion
- Over 8 Billion are invested worldwide by
governments and industry for RD

14Major Players in Nanotech
- 21st Century Nanotechnology Research and
Development Act was put in action.
- These organizations use governmental funding for
nanotechnology
- National Science Foundation
- Department of Defense
- Department of Energy
- NASA
- National Institutes of Health
15Industries Using Nanotech
- The numbers of companies who use Nanotech
increased 111 from 2004-2006
- The following industries have implemented
Nanotech
- Clothing
- Automobile
- Chemical/Pharmaceutical
- IT and Optical
- Food and Beverage
16Industries (Contd)
- Clothing - Eddie Bauer Stain repellent khakis
- Automobile GM Light weight parts, rust proof,
and scratch resistant.
- Medical/Health AngstroMedica Synthetic Bone
- Food and beverage Miller Plastic bottles that
minimizes the loss of carbon dioxide
17IT Industries
- Apple Mini Ipod converted to Ipod Nano
- InvenSense Gyroscope ( Used to steady camera
phones)
- Intel/IBM Reinventing smaller computer chips
- HP is currently trying to reinvent computing
beyond today's silicon and transistors
18Present
Future
19Much like electricity and computers,
nanotechnology will influence all aspects of
life including information technology, medicine,
and solar technology.
20Future of NanotechnologyDid you know that its
predicted that by the year 2020 your wristwatch
will be smarter than you?
21Nanotechnology in Computers
- Currently CPUs and similar products cant get
much smaller with existing technology.
- Nano chips will allow for computers to be
smaller, more powerful, more efficient, and
cheaper.
- Allows for greater global communication,
cross-cultural understanding, and cooperation.
22Stunning Changes in Medicine
- Ability to target diseased or cancerous cells,
making them easier to locate.
- Makes medicines work faster
- Changing our understanding how proteins interact
with DNA and other biological molecules
- Modify genes to eradicate diseases
- Alzheimers, liver, heart, alcoholism etc.
23Repairing Molecular/ Cellular Damage
- Infectious Diseases
- Nanorobots can occupy whole cell, whereas
enzymatic or immune defenses against infections
are more cautious.
- Cancer
- Nanorobots can potentially repair our DNA in
cells that have underwent mutations.
24Nanotechnology Against Cancer
- Nanotechnology is being applied to cancer in two
broad areas
- the development of nanovectors, such as
nanoparticles, which can be loaded with drugs or
imaging agents and then targeted to tumours
- high-throughput nanosensor devices designed to
detect the biological signatures of cancer.
- Combined, such technologies could
- lead to earlier diagnosis and better
- treatment for patients with cancer.
25Changes in Medicine (cont.)
- Nanotechnology has allowed for functional
clothing, existing examples include bug
repellant shirts, antimicrobial underwear and
stain-resistant trousers. - The possibilities are endless, imagine a world
where no one gets seriously ill, grows older, or
even dies until they want to!
26Maximizing Productivity of Agriculture
- Precision farming using nanosensors, pest
nanocides, and inexpensive decentralized water
purification.
- Even more advanced would be plant gene therapy
and pest resistant, high yield crops that require
less water.
- Food technology
- Crop disease control and management
- Food quality and safety
- Demands on food packaging
27NanoSolar Technology
- Scientists have developed new ways to utilize
solar energy.
- Benefits and Improvements
- 1/3 the cost of traditional solar cells
- Lighter weight and less bulk, paper thin panels
- Greater efficiency, current silicon cells are
poor absorbers of solar energy
- One minute of sunlight would be enough to meet
the worlds energy demand for a year.

28Going Green
- It is predicted that by 2050 our world population
will be 8.9 billion, causing bigger demands on
agriculture.
- Nanotech can provide these solutions
- Nanosensors making pollution monitoring
affordable
- Light weight lower energy needs
- Reducing uses of harsh cleansers
