Superparamagnetic Gadolinium Ferrite Nanoparticles with Controllable Curie Temperature – Cancer Theranostics for MR‐Imaging‐Guided Magneto‐Chemotherapy

A facile polyol approach for preparing low‐Curie‐temperature ( T C ) gadolinium‐doped iron oxide nanoparticles (GdIO NPs) for targeted magnetic hyperthermia and chemotherapy coupled with T 1 – T 2 dual‐model magnetic resonance (MR) imaging (where T 1 and T 2 are the longitudinal and transverse relaxation times, respectively) is reported. A small amount of Gd doping decreases the T C of iron oxide down to about 400 K. In the presence of...
