What is Nanoscience?
Nanoscience is the science of very small particles.
Nanoscience looks at the properties of
nanoparticles.
These are particles with in the range of 0·1nm to 100nm.
The name 'nano' means 10-9.
A nanometre is one millionth of a millimetre. It is written nm.
1nm = 0·000000001
metres.
Nanotechnology looks at the new uses of these small particles.
There are many examples
of nanoparticles including
sea spray and particulates.
The table below shows the sizes
of
some things listed in the left column.
The bottom four are in the range of nanoparticles.
