Nanoparticles

Nanoparticles are between 1 and 100 nanometres (nm) in size and are made up of a few hundred atoms.

A nanoparticle has a very large surface area compared to its volume.

The properties of nanoparticulate substances are different from those of the same atoms in bulk such as powders, lumps or sheets.

One nanometre is 1 × 10-9m or 0.000000001 m.
