| 论文摘要 | Attributed to its simplicity, noninvasive features, and excellent therapeutic effect, phototherapy has recently received considerable interest. The combination of photothermal therapy (PTT) and photodynamic therapy (PDT) holds great promise in the treatment of tumors, and in order to achieve satisfactory antitumor efficacy, suitable photosensitizers are a prerequisite. In this paper, highly monodispersed covalent organic framework (COF) nanoparticles were first prepared by a mild solution-phase synthesis method at room temperature. The as-synthesized nonporphyrin containing COF nanoparticle was employed as a novel photosensitizer for PDT, which exhibited an excellent photodynamic effect under 650 or 808 nm laser irradiation. Then, CuSe nanoparticles, an ideal photothermal agent, were successfully conjugated with COF to form a dual functional photosensitizer for phototherapy. The resultant COF-CuSe platform possesses an excellent synergistic photothermal and photodynamic effect. The in vitro and in vivo experiments indicated an enhanced therapeutic effect on killing cancer cells and inhibiting the tumor growth. This work demonstrates the great potential of nonporphyrin containing COF as a photosensitizer for photodynamic cancer therapy and provides a facile and efficient approach to construct COF-based multifunctional theranostic agents for cancer diagnosis and treatment by combining COFs with other functional materials. |
