Microcapsule for local treatment of a tumor and method for positioning a magnetic gradient field guiding magnetic nanoparticles to a target location as well as apparatus for positioning a magnetic gradient field

摘要

A microcapsule for the local treatment of a tumor is proposed. The microcapsule has a support material forming a casing for the microcapsule, an active agent that damages tumor cells, a marker material suitable for use as an x-ray marker, and at least one magnetic nanoparticle. The active agent in particular destroys the tumor cells.
