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 billionth of a meter.

Some of the disadvantages of

are; • . In relation to health problems, it is so

minute that its existence in the hand is much

unnoticed.

Global monetary crisis, loss of jobs, oil becomes worthless, diamonds become worthless, atomic weapons more destructive and accessible

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

However, the nature and extent of risk to consumer health from ingestion of nanoparticles via food and drink are largely unknown.

• Possible dangers:– Environment

– water =>fish– soil =>bacteria– air =>animals,

humans

– Lungs– PM .01?– New asbestos?

– Intestines– inflammation?

– Skin

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?

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 commonly held within and outside of research communities, primum non nocere.

Academic integrity, research ethics, consideration of occupational and public health issues

Second Dimension

Negotiable moral claims, subject to change based on perception.

Who will control emerging technologies, and for what purpose? What will happen to personal privacy? Should technological developments ever be “rushed?”

Third Dimension Meta-ethical understandings of the purpose of human living, beliefs about existence: meaning, selfhood, purpose.

What is the moral good of progress? What will these changes mean for emotional, spiritual, psychological well-being of the human-family?
