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.
