Biocompatible Superparamagnetic Iron Oxide Nanoparticle Dispersions Stabilized with Poly(ethylene glycol)-oligo(aspartic acid) Hybrids

摘要

MPEG-oligo(aspartic acid) hybrid copolymers were synthesized and used as the stabilizer to prepare iron oxide nanoparticles dispersions in water. The iron oxide nanoparticles dispersions are stable in physiological conditions and possess low cytotoxicity and good biocompatibility.
