| 摘要 |
An encapsulated chelate dendritic polymer and an encapsulated ligand dendritic polymer are disclosed which have unique properties. These encapsulated chelate dendritic polymers may have associated with its dendritic polymer surface target directors, proteins, DNA, RNA (including single strands) or any other moieties that will assist in diagnosis, therapy or delivery of this encapsulated chelate dendritic polymer. These encapsulated dendritic polymers are suitable as contrast agents for use in imaging in an animal, for other imaging techniques, for EPR, and as scavenger agents for chelant therapy. Formulations for these uses are also included within the scope of this invention.
