Claim Text:
1. An iodine-containing radial-shaped macromolecule comprising: a core composed of a circular or spherical symmetric small molecular compound, or a radial-shaped macromolecule; an iodine-containing compound bound to the core directly or through a peptide; and a biocompatible polymer bound to the core directly or through a peptide, or directly bound to the iodine-containing compound bound to the core, wherein the iodine-containing radial-shaped macromolecule has a structure in which the biocompatible polymers form a protective layer to prevent the exposure of the core and the iodine-containing compound in vivo; and the core has one or more surface functional groups selected form the group consisting of amine, hydroxyl, hydroxylamine, carboxyl, carboxyhydrazide, hydrazine, thiol, azide, alkynyl, halogen, aldehyde, ketone, epoxy, 3-carbomethoxypyrrolidinone, and tri-(C
