The nanoscale

The nanoscale

Size scale from an atom to a nanoparticle and dust, with a surface-area comparison between a bulk solid and many nanoparticles

A nanoparticle is a particle between about 111 and 100 nm100 \, \text{nm}100nm across. An atom is roughly 0.1 nm0.1 \, \text{nm}0.1nm across, so a nanoparticle is far larger than an atom but far smaller than a speck of dust.
