2. Nanotechnology
Birth of Nanotechnology
• Professor Taniguchi of Tokyo Science University used the word
“nanotechnology” to describe the science and technology
of processing or building parts with nanometric tolerances.
•A nanometer is a unit of length in the metric system, equal to one
2
billionth of a meter.
10. Some of the disadvantages of

• . In relation to health problems, it is so
minute that its existence in the hand is
much unnoticed.
However, the nature and extent of

•The risk of inhaling this could
be very dangerous, due to
which it can be a cause of
death.

13. Introduction nanotechnology
• Possible dangers:
– Environment
– water =>fish
– soil =>bacteria
– air =>animals, humans
– Lungs
– PM .01?
– New asbestos?
– Intestines
– inflammation?
– Skin 13
14. Introduction nanotechnology
• Problems:
– Mass: NP are very tiny, => traditional dose-
response does no longer apply.
– Toxicology: effects of NP may differ. A
knowledge gap exists.
– Detection : due to the size of NP and lack of
knowledge detection is difficult.
– Law: current legislation is in place on all
chemicals, but how does one control an
undetectable substance?

20. Dimensions of “nano-ethics”
• Ethical implications of NT are as broad as the field itself
• Berne (2006) uses a three-dimensional framework for thinking about ethics related to NT
First Dimension Moral assertions Academic integrity, research
commonly held within ethics, consideration of
and outside of occupational and public health
research communities, issues

Second Negotiable moral Who will control emerging

technological developments ever
be “rushed?”
Third Dimension Meta-ethical What is the moral good of
