What is a Nanoparticle?
The simple answer to this question is any particle less than 100 nm. But like most things in particle technology a more thorough discussion is required to achieve an unambiguous and complete response. The experts from the ISO and ASTM standards shown below provide additional nuances to the definition. The current agreement among the standards groups is that the scale from 1 – 100 nm defines the size range of a nanoparticle. Below 1 nm may be excluded in order to avoid calling clusters of atoms a particle, but the literature contains references to particles < 1 nm. Since particles are three dimensional the ASTM standard defines two or three dimensions must be between 1 – 100 nm. This provides for nanotubes with a diameter of 10 nm, but a length > 100 nm.
