What’s nanotechnology?
What’s nano-?
 centi meter (cm 釐米 )=0.01 meter
 centi= one hundredth (of sth)
 nano meter (nm 奈米 )=0.000000001 meter
 nano= one billionth (of sth)

The size of a nanometer
A marble vs. The Earth
= A nanometer vs. A meter

DNA
= 1 nm

An atom = 0.1 nm

Now, what is nanotechnology?
 If a technology can deal with materials as small as a nanometer
(such as an atom), we call it nanotechnology.
