Long before 'nanoparticle' became a common term, polymer scientists were already working at the nano scale (<100nm) with polymer macromolecules. Determining the accurate size at that scale is a challenge and often different applications will require different technical solutions. In the second webinar in this series, we will look at measurement of polymer molecular size in solution. The focus is on light scattering techniques including DLS and MALS.
