Abstract Compared to conventional photothermal therapy (PTT) which requires hyperthermia higher than 50 °C, mild‐temperature PTT is a more promising antitumor strategy with much lower phototoxicity neighboring normal tissues. However, the therapeutic efficacy of always restricted by thermoresistance cancer cells. To address this issue, supramolecular drug nanocarrier fabricated co‐deliver nitric oxide (NO) and agent DCTBT NIR‐II aggregation‐induced emission (AIE) characteristic for PTT. NO can be effectively released from nanocarriers in intracellular reductive environment capable simultaneously producing reactive oxygen species (ROS) upon 808 nm laser irradiation. The generated ROS further react produce peroxynitrite (ONOOˉ) bearing strong oxidization nitration capability. ONOOˉ inhibit expression heat shock proteins (HSP) reduce cells, necessary achieve excellent DCTBT‐based at mild temperature (<50 °C). performance ONOOˉ‐potentiated validated on subcutaneous orthotopic hepatocellular carcinoma (HCC) models.

The development of covalent organic framework (COF) sonosensitizers with intrinsic sonodynamic effects is highly desirable. However, such COFs are generally constructed using small-molecule photosensitizers. Herein, we report that the reticular chemistry-based synthesis from two inert monomers yields a COF-based sonosensitizer (TPE-NN) inherent activity. Subsequently, nanoscale COF TPE-NN fabricated and embedded copper (Cu)-coordinated sites to obtain TPE-NN-Cu. Results show Cu coordination can enhance effect TPE-NN, whereas ultrasound (US) irradiation for therapy augment chemodynamic efficacy Consequently, TPE-NN-Cu upon US shows high-performance anticancer based on mutually reinforced sono-/chemo-nanodynamic therapy.
