Magnetic Heating

Localized heat induction using magnetic nanoparticles under an alternating magnetic field is an emerging technology applied in areas including, cancer treatment, thermally activated drug release and remote activation of cell functions. To enhance the induction heating efficiency of magnetic nanoparticles, the intrinsic and extrinsic magnetic parameters influencing the heating efficiency of magnetic nanoparticles should be effectively engineered. This review covers the recent progress in the optimization of magnetic properties of spinel ferrite nanoparticles for efficient heat induction. The key materials factors for efficient magnetic heating including size, shape, composition, inter/intra particle interactions are systematically discussed, from the growth mechanism, process control to chemical and magnetic properties manipulation.

ABSTRACTMagnetic hyperthermia is a non-invasive cancer treatment method which is used synergistically with the current cancer treatments. Improved biocompatibility and enhanced heating characteristics are the pressing challenges to be addressed in magnetic hyperthermia. Through a novel combinatorial approach, we have attempted to address both the challenges. Ferrimagneticmagnetite nanoparticles (FMNPs)of size 50 nm were synthesized by thermal decomposition method and were converted to hydrophilic phase by 3-Aminopropyltrimethoxysilane (APTMS). Serum Albumin (SA) from rat was conjugated over the APTMS-FMNPs to convert to biocompatible phase. The preliminary haemolysis experiments show that SA-FMNPs are non-haemolytic (1.2 % haemolysis). It is observed from the magnetic heating experiments that due to better colloidal stability, the Specific Absorption Rate value of the SA-FMNPs are higher (2100 W/g) than the FMNPs without SA (1400 W/g). Thus we report here that SA conjugation over FMNPs (with a high saturation magnetization of 75 emu/g) provides a novel combinatorial approach to enhance both the biocompatibility and the SAR value for magnetic hyperthermia.
