Endogenous oxygen generating multifunctional theranostic nanoplatform for enhanced photodynamic-photothermal therapy and multimodal imaging

Phototherapy, including photothermal therapy (PTT) and photodynamic therapy (PDT), has been considered as a noninvasive option for cancer therapy. However, insufficient penetration depth, tumor hypoxia, and a single treatment method severely limit the effectiveness of treatment. Methods: In this study, a multifunctional theranostic nanoplatform has been fabricated based on Au/Ag-MnO2 hollow nanospheres (AAM HNSs). The Au/Ag alloy HNSs were first...
