## Executive GIST (TL;DR)
- The authors developed a near‑infrared light‑triggered nanoplatform (UCNPs@SiO2‑MB@PDA) combining **upconversion nanoparticles (UCNPs)**, a silica shell loaded with methylene blue (MB), and a polydopamine (PDA) outer layer for synergistic tumor treatment. - Under 980 nm excitation, UCNPs emit red light that activates MB via luminescence resonance energy transfer to generate **singlet oxygen**, enabling **photodynamic therapy (PDT)**. - The PDA shell absorbs multiple emission bands from UCNPs and converts light to heat, producing **photothermal therapy (PTT)** with a reported photothermal conversion efficiency of **35.6%**. - The nanoplatform was synthesized using UCNP cores, an inverse microemulsion approach to form the silica shell and load MB, and final surface modification with PDA. - In vitro experiments on HeLa cells showed good **biocompatibility**, efficient cellular internalization, and superior cytotoxicity under NIR irradiation compared with monotherapy. - At 200 μg/mL under near‑infrared light, HeLa cell survival fell to **18.9%**, indicating a strong synergistic antitumor effect. - Live/dead staining supported the combined PDT/PTT antitumor activity of the material. - The authors conclude the platform offers a promising strategy for precise treatment of deep tumors by combining **near‑infrared activation**, **PDT**, and **PTT** in a single nanoplatform. - Conflict of interest: authors declared no competing interests.

Here, we developed a near-infrared light-triggered nanoplatform (UCNPs@SiO₂-MB@PDA) for synergistic photodynamic therapy (PDT) and photothermal therapy (PTT) of deep tumors. The nanoplatform takes the UCNPs as the core, wraps the silica shell loaded with the photosensitizer MB via the inverse microemulsion method, and finally modifies the surface of the PDA. Under 980 nm excitation, the red light emitted by the UCNPs can effectively activate MB to produce singlet oxygen through luminescence resonance energy transfer, achieving PDT. At the same time, the PDA shell can efficiently absorb the multiband emitted light of the UCNPs and convert it into thermal energy, achieving PTT with a photothermal conversion efficiency of 35.6%. In vitro cell experiments have shown that the material has good biocompatibility and can be effectively internalized by tumor cells. Under near-infrared light irradiation, its killing effect on HeLa cells was considerably better than that of monotherapy, and the cell survival rate decreased to 18.9% when the cells were exposed to a concentration of 200 μg/mL. The results of the live/dead cell staining further confirmed the excellent synergistic antitumor performance of these materials. This work offers a promising strategy for the precise and effective treatment of deep tumors. **Keywords:** Near-infrared light; Photodynamic therapy; Photothermal therapy; Synergistic antitumor performance.
