The nanoscale

Nanoscience studies structures on the scale of approximately 1 nm1 \, \text{nm}1nm to 100 nm100 \, \text{nm}100nm. In this lesson, particle-size bands do not overlap: nanoparticles have diameters from 1 nm1 \, \text{nm}1nm to less than 100 nm100 \, \text{nm}100nm, fine particles from 100 nm100 \, \text{nm}100nm to less than 2500 nm2500 \, \text{nm}2500nm, and coarse particles from 2500 nm2500 \, \text{nm}2500nm to 10,000 nm10{,}000 \, \text{nm}10,000nm.
