Tumor‐Targeted Exosome‐Based Heavy Atom‐Free Nanosensitizers With Long‐Lived Excited States for Safe and Effective Sono‐Photodynamic Therapy of Solid Tumors

Advanced Healthcare Materials, EarlyView.
Engineered exosome‐based heavy atom‐free nanosensitizers are developed for safe and targeted sono‐photodynamic therapy of solid tumors. The IR820‐TPE‐loaded, biotin‐conjugated exosomes (IR820‐TPE@B‐Exo) demonstrate significant promise for NIR fluorescence imaging‐guided sono‐photodynamic cancer therapy.

Si Inhibited Osteoclastogenesis: The Role of Fe and the Fenton Reaction

Advanced Healthcare Materials, EarlyView.
Silicate (Si) inhibition of osteoclastogenesis, is mediated by Fe. Si chemical interactions with Fe inhibit the Fenton reaction and intercellular ROS availability. This reduction in ROS availability inhibits osteoclastogenesis. The addition of Fe, in Si‐inhibited osteoclast cultures, restores the Fenton reaction, and osteoclastogenesis.

Immunosuppressive Cytokine‐Tethered Hydrogel for Treating Rheumatoid Arthritis

Advanced Healthcare Materials, EarlyView.
An injectable hydrogel is developed by chemically tethering IL‐4, an immunosuppressive cytokine, to a hyaluronic acid‐based backbone. The hydrogel reduces joint friction and exerts immunomodulatory effects. In a rheumatoid arthritis (RA) mouse model, it reduced inflammation, preserved cartilage, and promoted anti‐inflammatory immune responses.

Digitonin‐Loaded Nanoscale Metal–Organic Framework for Mitochondria‐Targeted Radiotherapy‐Radiodynamic Therapy and Disulfidptosis

Advanced Materials, EarlyView.
A mitochondria‐targeted cationic nanoscale metal organic framework shows strong radiotherapy‐radiodynamic therapy effects and selectively releases digitonin in acidic tumor microenvironments to induce disulfidptosis of cancer cells and downregulate immune checkpoints in cancer and T cells, thereby eliciting strong antitumor immunity to effectively ...
