Highly water-dispersed superparamagnetic magnetite colloidal nanocrystal clusters from multifunctional polymeric nanoreactors: synthesis and properties

Abstract

Uniform superparamagnetic Fe₃O₄ colloidal nanocrystal clusters were <italic>in situ</italic> fabricated by using novel water-soluble multi-arm star-shaped brush-like block copolymers of (PEO-<italic>g</italic>-PAA)-<italic>b</italic>-PEO as multifunctional polymeric nanoreactors.
