What 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!

3
Early 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.

4
Early 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.

5
Richard Feynman
  • A well-known physicist
  • Theorized building machines to manufacture at
    atomic levels
  • Predicted information could be stored at great
    density at atomic levels

6
Norio Taniguchi
  • Tokyo professor
  • In 1974 coined the term nano-technology in a
    paper On the basic concept of Nano-technology

7
Eric Drexler
  • In late 1970s, began to invent molecular
    manufacturing
  • Understood molecular machines could manufacture
    complex chemical products
  • Introduced the term nano-technology

8
Historical 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.

9
Historical 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.

10
Historical 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.

11
Historical 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.

12
Current 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

Major 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

15
Industries 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

16
Industries (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

17
IT 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

Present
Future
19
Much like electricity and computers,
nanotechnology will influence all aspects of
life including information technology, medicine,
and solar technology.
20
Future of NanotechnologyDid you know that its
predicted that by the year 2020 your wristwatch
will be smarter than you?
21
Nanotechnology 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.

22
Stunning 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.

23
Repairing 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.

24
Nanotechnology 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.

25
Changes 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!

26
Maximizing 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

27
NanoSolar 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.

28
Going 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
