Pt Decorated Ti3C2T MXene with NIR-II Light Amplified Nanozyme Catalytic Activity for Efficient Phototheranostics.The clinical application of photothermal therapy (PTT) is severely limited by the tissue penetration depth of excitation light, and enzyme therapy is hampered by its low therapeutic efficiency.  Meanwhile, the composite shows a desirable photothermal effect upon NIR-II light irradiation with a low power density (0.75 W cm-2).  Especially, the POD-like activity is significantly enhanced by the elevated temperature arising from the photothermal effect of Ti3C2T.  This work may provide an approach for hyperthermia-amplified nanozyme catalytic therapy, especially based on metal catalysts and MXene nanocomposites.
