Caption

Figure | J-Type Assembled Pt(IV)-Coordinated Carbon Dots for Near-Infrared Light-Triggered Pyroptosis. a, representative AC-HAADF-STEM image of the HS-Pt-CDs. b, Absorption spectra of Pt-CDs, HS-Pt-CDs and TEM image of hollow-like HS-Pt-CDs (insets). The intelligent metasurface has two operational modes: active and passive modes. c, Illustration of energy level diagrams of the Pt-CDs and HS-Pt-CDs, and a possible NIR light triggered photocatalytic mechanism for HS-Pt-CDs in aqueous solution. d, Schematic illustration of photocatalytic HS-Pt-CDs that promote the NIR-triggering Pt(II) species release and ROS to trigger tumor pyroptosis to prevent cancer metastasis.
