 What is nanotech?  Nanotechnology :  Art and sience of manipulating atoms and moleculs to create new systems, materials and devices.  Nanotechnology is the engineering of functional systems at the molecular scale.

 Size matters  How big is nano? Nano = x’s smallr than the diameter of human eye  Examples of Nanoscale:  A cubic micron of water contains about 90 billions of atoms.  1 millimeter has 1000 micron  Micron is a thousand times larger than nano

 Nanotechnology’s development

NanotechnologyNanotechnology Nanotechnology is a group of emerging technologies in which the structure of matter is controlled at the nanometer scale, the scale of small numbers of atoms, to produce novel materials and devices that have useful and unique properties.

 General purpose technology Imagine a medical device that travels through the human body to seek out and destroy small clusters of cancerous cells before they can spread. Or a box no larger than a sugar cube that contains the entire contents of the Library of Congress. Or materials much lighter than steel that possess ten times as much strength. — U.S. National Science Foundation

 Multi use technology

Benefits of nanotech Benefits: - water - computers - electrical power - solar power - medicine

Risks of nanotechnology  Risks: - monopoly - high price of products - criminal and terrorism - nanotech weapons

Some important questions Who will own the technology? Will it be heavily restricted, or widely available? What will it do to the gap between rich and poor? How can dangerous weapons be controlled, and dangerous arms races be prevented?
