Multifunctional magnetic nanoparticles have gained ample attention in the field of nanomedicine in recent years. Here, novel superparamagnetic core-shell manganese ferrite nanoparticles (MFNP)-encapsulated mesoporous silica nanoparticles (MSMFNPs) loaded with anticancer drug doxorubicin (DOX) for the combined application of hyperthermia and chemotherapy were developed and tested in vitro. Our results indicate that DOX-MSMFNPs achieved a favorable hyperthermic response in an alternating magnetic field in addition to cancer cell-specific cationic DOX release due to the cleavage of amide bonds under acidic pH, and synergistically contributed towards an enhanced tumoricidal effect.
