“Nano” – From the Greek word for “dwarf”and means 10-9, or one-billionth. Here it refers to one-billionth of a meter, or 1 nanometer (nm).
1 nanometer is about 3 atoms long.
“Nanotechnology” – Building and usingmaterials, devices and machines at the nanometer (atomic/molecular)scale, making use of unique properties that occur at those small dimensions.
Why is Small Good?
-Faster
-Lighter
-Can get into small spaces
-Cheaper
-More energy efficient
-Different properties at very small scale
