Drug-loaded embolic agent

The development of injectable microcapsules for delivery of chemotherapy agents remains an active area of research. The ultimate goal is to achieve targeted delivery of chemotherapy agents to specific sites in the body, ideally by injection of drug-loaded microcapsules that would seek out and destroy diseased cells. Intra-arterial infusion chemotherapy is a direct approach to targeted delivery. The clinical applications of microspheres and microcapsules in embolization and chemotherapy have been assessed (41).
