What is Nanotechnology?

Nanotechnology is the study of what happens when things get very, very small – only a few atoms in size. The word “nanometer” means one billionth of a meter, perhaps five or six atoms long. At the nanoscale, materials can have very different physical or chemical properties, even though they are the same. In particular, super thin films of material, only a few nanometers thick, can cause interference within light reflecting off them, resulting in beautiful displays of colors.
