چکیده انگلیسی
Cell membrane-camouflaged nanoparticles for cancer therapy have received a burgeoning interest over the past years. However, the low drug loading and intratumoral release efficiency, and lack of precise targeting remains a big challenge; in addition, foreign carriers used may pose an expected burden in the course of metabolism. In this study, we designed and fabricated a novel NIR-responsive highly targeted carrier-free nanosystem by coating the exactly identical source of cracked cancer cell membranes (CCCMs) specifically derived from the homologous tumors onto the surface of the co-assembly nanoparticles of doxorubicin (DOX) and FDA-approved photothermal agent, indocyanine green (ICG). The nanosystems exhibited a high drug loading capacity (89.8%), cancer cell self-recognized ability and immune escape function. Further, the nanodrugs could be efficiently released for the membrane disturbance triggered by photothermal effect of ICG under NIR irradiation. The tumor-bearing mice model demonstrated that the self-carried DOX NPs@ICG@CCCM nanoparticles possessed a strong synergistic chemo-/photothermal therapeutic efficacy against tumors in vivo. The present strategy could be developed as a universal approach for designing and constructing carrier-free theranostic nanovehicles by intentionally selecting specific cancer cell membrane and the inner loading cargoes.
