    Achieving a desired whitening effect through short treatments without using peroxide and without compromising the integrity of tooth enamel remains a challenge in teeth whitening. Here, we developed a highly safe and efficient photodynamic therapy (PDT) strategy based on visible light-activated bismuth oxyiodide nanoparticles for nondestructive tooth whitening. The Bi7O9I3 nanoparticles (NPs) exhibited efficient photocatalytic activity owing to their narrow band gap, effectively harnessing the broad spectrum of visible light to generate ample electrons and holes. Meanwhile, the presence of oxygen vacancies, low oxidation state Bi3+ and the high specific surface area endow Bi7O9I3 NPs with effective electron-hole separation ability and potent redox potentials. Empowered by these characteristics, Bi7O9I3 NPs effectively catalyzed O2 into radicals (O2•-), facilitating the degradation of dental surface pigment molecules for tooth whitening. Concurrently, they eradicated oral bacteria and bacterial biofilms adhering to tooth surfaces, thereby having a positive effect on the effectiveness of tooth whitening. This PDT strategy with Bi7O9I3 NPs shows broad application prospects in tooth whitening.

    通过短期治疗实现理想的美白效果，而不使用过氧化物并且不损害牙釉质的完整性，在牙齿美白领域一直是一个挑战。在这里，我们开发了一种基于可见光激活的铋碘酸盐纳米粒子的高效且安全的光动力疗法（PDT）策略，用于非破坏性牙齿美白。由于其窄带隙，Bi7O9I3 纳米颗粒（NPs）表现出高效的光催化活性，能够有效利用可见光的宽谱范围来生成大量电子和空穴。同时，氧空位的存在、低氧化态的Bi3+ 以及高的比表面积赋予 Bi7O9I3 NPs 强效的电子-空穴分离能力和显著的氧化还原电势。凭借这些特性，Bi7O9I3 NPs 有效地催化 O2 形成自由基（O2•-），促进了牙面色素分子的降解，实现牙齿美白。同时，它们还消除了口腔细菌和附着在牙齿表面的细菌生物膜，从而对牙齿美白的效果产生了积极影响。这种使用 Bi7O9I3 NPs 的 PDT 策略在牙齿美白领域具有广阔的应用前景。
