Metal-Polyphenol Self-Assembled Nanophotothermal Agent for Precise Mitochondrial Targeted Photothermal Therapy

exhibits magnetic resonance imaging (MRI) functionality, which combined with the fluorescence imaging of IR780 endows TR with multimodal imaging capabilities. In addition, TR is easy to release photosensitizers through acid response in the low pH environment of TME, and achieves precise damage to mitochondria through mitochondrial anchoring and light regulation. This overcomes the drawbacks of traditional tumor treatment methods, such as poor specificity, and demonstrates efficient and controllable antitumor activity.
