Nanotechnology

Nanotechnology:

1.Nano, Greek for “dwarf,” means one billionth.
Measurement at this level is in nanometers
(abbreviated “nm”) — billionths of a meter.
To put this into perspective, a strand of human
hair is roughly 75,000 nm across.
Ten hydrogen atoms lined up end-to-end
to make up 1 nm.
2.Scanning tunneling microscope,
enabling researchers to both see and
manipulate atoms for the first time.
