CARBON NANOHORN FOR ENCAPSULATING AND CARRYING BORON COMPOUND ON OUTER WALL, AND METHOD FOR PRODUCING CARBON NANOHORN

摘要

The purpose of the present invention is to overcome the problem of low tumor accumulation of boron in a boron formulation used in conventional boron neutron capture therapy, and to provide a boron formulation having high boron tumor accumulation; using carbon nanohorns for encapsulating a boron compound (BN-CNH) as the active ingredient of a boron neutron capture therapy formulation makes it possible to deliver the boron compound selectively to the tumor cells and to raise the boron tumor accumulation. This BN-CNH is preferably produced using ammonia borane as a raw material by heating together with carbon nanohorns.
