The question
that I'm answering today
is about what's the difference
between the nanoscale
and the atomic scale?
Actually, the atomic scale
is smaller than the nanoscale.
So, when we talk
about nanotechnology,
typically we look
at dimensions
between one
and one hundred nanometers.
So somewhere between
atomic spacings
and then cell sizes.
If we're talking
about atomic scale,
we really look
at the size of atoms,
which is below one nanometer.
So, nanoscale--between one
and one hundred nanometers,
atomic scale--
below one nanometer.
