This study aims to establish a drug delivery system combining PDT and chemotherapy to show that chemotherapeutic drugs provide oxygen to PDT, while PDT promotes the release of chemotherapeutic drug.Methods: Firstly, poly(ethylene glycol)-lysine(Ce6)-block-poly(L-glutamate)-imidazole (mPEG-lys(Ce6)-PGA-AIM) was synthesized and self-assembled into micelles that exhibited pH- and ROS-responsiveness and buffering capacity. Perfluorohexanoate-modified cisplatin (FCP), as oxygen carriers, was encapsulated into mPEG-lys(Ce6)-PGA-AIM micelles. Then, the properties of micelles and their biological functions in vivo and in vitro were investigated.Results: The micelles exhibited remarkabe stability, pH regulated drug release, good biocompatibility and effective tumor penetration. Cellular uptake demonstrated the efficient endosome/lysosome escape of CFMs, which facilitates the intracellular drug release. Both in vitro and in vivo experiments reflected that CFMs with laser irradiation showed significantly improved therapeutic activity compared with single PDT or chemotherapy.Conclusion: Chemotherapy and PDT were combined in the form of mutual assistance to provide a promising strategy for clinical treatment.Keywords: chemotherapy, photodynamic therapy, dual-responsiveness, oxygen carriersChen YZhang LLi FSheng JXu CLi DYu HLiu WDove Medical Pressarticlechemotherapyphotodynamic therapydual-responsivenessoxygen carriersMedicine (General)R5-920ENInternational Journal of Nanomedicine, Vol Volume 16, Pp 3679-3694 (2021)
