摘要
Abstract Nanocatalytic therapeutic agents with triple synergistic treatment modes of chemodynamic therapy (CDT), photothermal therapy (PTT) and photodynamic therapy (PDT) are emerging nanomaterials in malignancy treatment. Nevertheless, the passive diffusion and transport of nanomaterials result in poor permeability in tumor lesions, severely affecting the effectiveness of synergistic therapy. Herein, a dual‐source‐driven parachute‐like Au 2 Pt@PMO@ICG Janus nanomotor (APIJNS) is prepared by an interfacial energy‐mediated anisotropic growth strategy for PTT‐mediated CDT/PDT triple synergistic cancer therapy. Such nanomotor can realize self‐thermophoresis drive under the trigger of near‐infrared light, which can effectively enhance the active permeability and uptake of the APIJNS in the tumor tissue, thus achieving efficient PTT/PDT/CDT synergistic therapeutic effect. In addition, parachute‐like APIJNS exhibits high‐efficiency catalase (CAT)‐like activity and can catalyze the overexpressed H 2 O 2 in the tumor microenvironment (TME) to generate oxygen (O 2 ), not only alleviating the hypoxia in the tumor lesion, but also converting it into singlet oxygen ( 1 O 2 ) to activate the photosensitizer ICG, achieving PDT. This work provides new ideas for enhancing triple synergistic cancer therapy by improving tumor permeability with dual‐drive Janus nanomotors based on dual noble metal nanozymes.
