Mitochondria‐Targeted ROS Scavenging Natural Enzyme Cascade Nanogels for Periodontitis Treatment via Hypoxia Alleviation and Immunomodulation

open access: yesAdvanced Science, Volume 12, Issue 29, August 7, 2025.
TPP‐SAT, a mitochondria‐targeted natural enzyme‐cascade nanogel, selectively scavenges mitochondrial ROS (e.g., H2O2/·O2⁻) and converts them into therapeutic O2 via enzymatic cascades, alleviating hypoxia and inflammation. It rebalances M1/M2 macrophage polarization, activates the Nrf2 pathway while suppressing NF‐κB, enhances antioxidant defenses, and
