Biomimetic approach offers numerous opportunities to design therapeutic platforms with enhanced antitumor performance and biocompatibility. Herein we report red blood cell membrane-camouflaged nanoparticles (RBC(M(TPC-PTX))) for synergistic chemo- and photodynamic therapy (PDT). Specifically, the inner core is mainly constructed by reactive oxygen species (ROS)-responsive PTX dimer (PTX2-TK) and photosensitizer 5,10,15,20-tetraphenylchlorin (TPC). In vitro experiments show that the prepared RBC(M(TPC-PTX)) is readily taken up into endosomes. Under appropriate light irradiation, the TPC can generate ROS, not only for PDT but also for triggering PTX2-TK cleavage and on-demand PTX release for chemotherapy. In vivo results show that the coating of RBC membrane prolongs blood circulation and improves tumor accumulation. The combination of chemo- and photodynamic therapy enhances anticancer therapeutic activity, and light-triggered drug release reduces systematic toxicity. All these characteristics render the described technology extremely promising for cancer treatment.

光活化红细胞膜伪装的二聚体前药纳米粒子的协同光动力/化学疗法。
仿生方法为设计具有增强的抗肿瘤性能和生物相容性的治疗平台提供了许多机会。在这里,我们报告红细胞膜伪装的纳米粒子(RBC(M(TPC-PTX)))的协同化学和光动力疗法(PDT)。具体而言,内核主要由反应性氧(ROS)响应的PTX二聚体(PTX 2 -TK)和光敏剂5,10,15,20-四苯基二氯(TPC)构成。体外实验表明,所制备的RBC(M(TPC-PTX))容易被内体吸收。在适当的光照射下,TPC不仅可以为PDT产生ROS,而且还可以触发PTX 2 -TK裂解和化学疗法按需释放PTX产生ROS 。体内结果表明,红细胞膜的涂层延长了血液循环并改善了肿瘤的积累。化学和光动力疗法的组合可增强抗癌治疗活性,光触发药物释放可降低系统毒性。所有这些特征使得所描述的技术极有希望用于癌症治疗。
