Wet Ball Milling Synthesis of Iron Oxide Nanoparticles for High‐Efficiency, Controllable Magnetic Hyperthermia in Ovarian Cancer

Advanced Materials Technologies, EarlyView.
A wet ball‐milling method is presented to synthesize iron magnetic nanoparticles and evaluate their magnetic hyperthermia performance. Optimized particles (∼270 nm, Ms ∼114 emu/g) achieve ∼50°C heating under clinically safe alternating magnetic fields, while pulsed‐field operation enables controlled temperature regulation (∼30°C).

Heat dissipation mechanism of magnetite nanoparticles in magnetic fluid hyperthermia

Journal of Magnetism and Magnetic Materials, 2009
We report the results of a study undertaken to determine properties of magnetite particles that disipate heat only through Neel relaxation. The magnetite samples we considered for the heat dissipation studies were found to dissipate heat through both Neel and Brownian relaxations.
