Monodispersity is a key property to control the self-assembly of colloidal particles, and is typically reached after fine-tuning of the synthesis conditions. Monodisperse particle fractions can also be separated from polydisperse suspensions via ultracentrifugation. This paper demonstrates the capability of isolating and characterizing suspensions of core-shell iron oxide-polymer nanoparticles with extremely low polydispersity (p < 0.01) and, thus, of complementing nanoparticle synthetic approaches in the pursuit of highly monodisperse materials.
