Study examines the problem of development of novel nanomaterials serving for boron 10B isotope delivery agents in Boron-Neutron-Capture-Therapy (BNCT). For this purpose, there is done a mini-review on Nano powder boron compounds especially prospective for BNCT; magnetic Nano carriers of the therapeutically active agents in general, delivery of which can be controlled by using of an external magnetic field; as well as methods of synthesis of nanocomposites comprising components of both kinds. Based on recent literature analysis, boron nitride and boron carbide Nano powders doped with ferromagnetic iron oxide nanoclusters are recommended for BNCT as effective delivery agents with good biocompatibility
