Abstract

Provided is an organic-inorganic hybrid composite of a polymerized cyclic nitroxide radical compound and inorganic nanoparticles. Such a composite is capable, for example, of maintaining a stable nanoparticle shape in gastric fluid, and can be used by itself or as a carrier for delivery of another drug to the intestines.
