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
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
A Nanometer is Extremely Small:If you could paint a gallon of paint one nanometer thick, how much area would it cover? A square 1.2 x 1.2 miles or 936 acres! That is almost 1,000 football fields. American Chemical Society
