| 摘要 |
A therapeutic particle comprises a particle comprising one or more therapeutic agents and one or more fibrin-avid peptide variants attached to the surface of the particle. A method for magnetically targeting a therapeutic agent toward a device in a subject, such as a temporarily introduced magnetizable catheter or an implanted stent, comprises administering the therapeutic particles to the subject and generating a magnetic field, which targets the magnetic particles toward the device. The affinity peptide-modified therapeutic particles may comprise an effective amount of an anti-proliferative agent, such as paclitaxel, to inhibit or prevent in-stent restenosis. |
