| 摘要 |
The present invention relates to novel compositions of polymer-coated paramagnetic particles, defined as paramagnetic particles non-covalently coated with polymeric materials, which optionally possess targeting ligands, therapeutic agents, or carrier ligands. By selecting from a variety of linker groups and targeting ligands the coated paramagnetic particles are suitable for a wide variety of methods for controlled delivery of the particles. The invention also relates to methods and uses of imaging, diagnosing, and treating diseased or cancerous tissue using the particles.
