摘要

Through rational design, in vivo supramolecular construction of nanodrugs could precisely proceed in the lesion areas, which may apparently improve the theranostic performance of nanomaterials. Herein, a tumor microenvironment-responsive theranostic nanoplatform (Ce6-GA@MnO2-HA-PEG) has been constructed to achieve in vivo supramolecular construction and enhance the therapeutic efficacy of combined phototherapy through intracellular reassembly. Under the tumor microenvironment, such nanoplatform could undergo the process of decomposition-reassembly and form in situ photothermal assemblies. The generation of assemblies would endow this nanoplatform with the capacity of photothermal therapy. Meanwhile, this nanoplatform could alleviate hypoxia and improve the therapeutic efficacy of photodynamic therapy. The results of in vitro and in vivo experiments reveal that tumors can be ablated efficiently by the designed nanoplatform under laser irradiation. In addition, fluorescence imaging and magnetic resonance imaging can be activated by the decomposition of MnO2 to realize tumor imaging in vivo. Therefore, this multifunctional nanoplatform exhibits the capacity for boosting dual-modal imaging-guided combined phototherapy through intracellular reassembly, which may propose a new thought in cancer theranostics.
