Establishment of Preparation Method for Magnetic Materials Having High Heat Generation Ability and its Biocompatibility

在交流磁场中具有高生热能力的磁性材料已被研究用于癌症组织的局部治疗的新型热凝疗法中。我们主要研究了(1)物理珠磨铁氧体材料的生热能力和生热机理，(2)具有高生热能力的新型Y_3Fe_5O_(12)基材料的生热能力和生热机理，以及(3)利用喷雾干燥法制备用于栓塞治疗的微球材料。

Magnetic materials having a high heat generation ability in an AC magnetic field have been studied for use in new thermal coagulation therapy for the local treatment of cancerous tissues. We mainly studied(1) Heat generation ability and heat generation mechanism for the ferrite materials obtained using physical beads milling,(2) Heat generation ability and heat generation mechanism for new Y_3Fe_5O_<12>-based material having high heat generation ability, and(3) Preparation of microsphere materials using spray dryer for embolization therapy application.
