Title: Nanotechnology


1
Nanotechnology
  • Technology of the Future

2
Major Aspects of Nanotechnology
  • What is it?
  • How did it come about?
  • What are the social implications?
  • What does this mean for the future?

3
Definitions
  • Nano means one billionth.
  • Nanotechnology - Deals with moleculues between
    one and one hundred nanometers in diameter.
    Manipulating individual atoms and manufacturing
    from the bottom up.

4
Major Aspects of Nanotechnology
  • What is it?
  • How did it come about?
  • What are the social implications?
  • What does this mean for the future?

5
History of Nanotechnology
  • E mc2
  • Atomic bomb
  • Biotechnology/Genetic Engineering
  • Quantum Physics
  • Nanophase materials

6
Nanotechnology Past and Present
  • (A) a hand holding a computer chip.
  • (B) computer chip
  • (C) living cell placed on the chip
  • (D) two nanocomputers beside the cell.
  • (E) shows an irregular protein from the cell on
    the lower right, and a cylindrical gear made by
    molecular manufacturing at top left.
  • (F) shows two atoms in the protein,
  • (G) reveals the nucleus of the atom as a tiny
    speck.
  • Below 35 xenon atoms spell out a familiar logo

A nano-motor manipulated by two laser beams
8
Major Aspects of Nanotechnology
  • What is it?
  • How did it come about?
  • What are the social implications?
  • What does this mean for the future?

9
Positive Effects on Society
Above Nanomachines could allow for cleaner
energy production
Right Nanomachines in the blood stream
patrolling for viruses
10
Positive Effects on Society (Medical Applications)
Nanomachines could travel through the bloodstream
11
Negative Effects on Society
12
Major Aspects of Nanotechnology
  • What is it?
  • How did it come about?
  • What are the social implications?
  • What does this mean for the future?

13
The Future with Nanotechnology
Left A nano-gear Right A nano-universal-joint
14
The Future with Nanotechnology
Above A nano-bearing Right A nano-factory
15
If it falls into the wrong hands
Genocide and ethnic cleansing (pictures from
Kosovo)
16
Some Final Thoughts
  • Still a young science, but could take off at any
    time
  • Presents wonderful opportunities
  • Presents terrible opportunities
