Co2+ doped zinc manganese ferrite nanoparticles for magnetic induction hyperthermia

Cobalt-zinc-manganese ferrite nanoparticles with the composition CoxZn 0.8-x Mn 0.2 Fe 2 O 4 (0 ≤ x ≤ 0.5) were prepared by the co-precipitation method. The elemental composition, crystal structure, particle size, and magnetic properties were investigated using ICP, XRD, FTIR, TEM, and VSM techniques. The synthesized nanoparticles were subjected to magnetic induction heating measurements to evaluate potential for magnetic induction hyperthermia. The temperature of the Co 0.2 Zn 0.6 Mn 0.2 Fe 2 O 4 nanoparticle suspension stabilized at 42.9 °C under the applied alternating magnetic field. The cytotoxicity essay analyses indicate the good biocompatibility of the nanoparticles, exhibiting a good candidate for conventional hyperthermia.
