Delivery of the photosensitizer Pc 4 in PEG-PCL micelles for in vitro PDT studies.

abstract：:Cisplatin (CDDP) is an effective anticancer agent for many solid tumors but has significant systemic toxicity limiting its use in many patients. We have designed a loco-regional delivery system to increase platinum levels in the lymphatics, where early metastasis is most likely to occur, while reducing systemic toxici...
