Cover Story: We successfully developed new a supramolecular polymer containing difunctional adenine-containing end groups that spontaneously self-assembles into nanosized spherical micelles in aqueous solution due to the presence of self-complementary hydrogen-bonded adenine interactions. Subsequently, a pro-photosensitizer and antitumor drug could be effectively encapsulated within supramolecular micelles, in order to achieve effective drug delivery combined with photo-chemotherapy. More importantly, pro-photosensitizer-loaded micelles exhibited significantly enhanced cellular uptake after visible light irradiation, and the light-triggered disassembly of micellar structures rapidly increased the production of reactive oxygen species within the cells, which thus accelerated apoptotic cell death. Thus, this newly developed photoresponsive nanocarrier could serve as a novel anticancer delivery system to effectively inhibit cancer growth and metastasis through the synergistic effect of chemo-photodyna
