New nanomaterials recently synthesized in our group are lanthanum manganite doped with silver ions. The unique feature of the doped manganites is the possibility to control their Curie temperature in the range of tumor hyperthermia interest (41-43oC). At its Curie temperature, a ferromagnetic particle loses its magnetic properties; this metal-insulator phase transition is tunable and reversible. New ferromagnetic particles adopt the superparamagnetic behavior and are comparable to iron oxide as an MRI contrast agents. The goal of this presentation is to introduce newly synthesized nanomaterials and create a new platform for highly controllable hyperthermia cancer therapy and imaging.
