1Nanotechnology
2Major Aspects of Nanotechnology
- What is it?
- How did it come about?
- What are the social implications?
- What does this mean for the future?
3Definitions
- 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.

5History of Nanotechnology
- E mc2
- Atomic bomb
- Biotechnology/Genetic Engineering
- Quantum Physics
- Nanophase materials
6Nanotechnology 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
7A demonstration on the molecular level
A nano-motor manipulated by two laser beams
8Major Aspects of Nanotechnology
- What is it?
- How did it come about?
- What are the social implications?
- What does this mean for the future?
9Positive Effects on Society
Above Nanomachines could allow for cleaner
energy production
Right Nanomachines in the blood stream
patrolling for viruses
10Positive Effects on Society (Medical Applications)
Nanomachines could travel through the bloodstream
11Negative Effects on Society
12Major Aspects of Nanotechnology
- What is it?
- How did it come about?
- What are the social implications?
- What does this mean for the future?
13The Future with Nanotechnology
Left A nano-gear Right A nano-universal-joint
14The Future with Nanotechnology
Above A nano-bearing Right A nano-factory
15If it falls into the wrong hands
Genocide and ethnic cleansing (pictures from
Kosovo)
16Some Final Thoughts
- Still a young science, but could take off at any
time - Presents wonderful opportunities
- Presents terrible opportunities
