American Chemical Society NCW 2012 Nanotechnology: The Smallest BIG Idea in Science! Your Name Your Affiliation Location or type of presentation Date of presentation
WHAT IS NANOTECHNOLOGY? AND WHY IS IT SUCH A BIG IDEA?
Nanotechnology: Small, Different, New The nanometer is extremely small. At the nanometer scale, materials may behave differently. We can harness this new behavior to make new technologies.

A Nanometer is Extremely Small. In the time it takes to read this sentence, your fingernails will have grown approximately one nanometer (1 nm) in length. American Chemical Society 6
A Nanometer is Extremely Small: If you could paint a gallon of paint one nanometer thick, how much area would it cover? American Chemical Society 7 ?
