A Piezo‐Mimetic Ionic Hydrogel Harnessing Joint Motion for Cartilage Repair

Advanced Science, EarlyView.
A piezo‐mimetic ionic hydrogel converts mechanical deformation into bioactive ionic currents via stress‐induced asymmetric ion migration. Coupled with sustained Mg2+ release, this mechano‐electrochemical platform bridges mechanical loading and cellular signaling, enabling load‐adaptive stimulation and enhanced cartilage regeneration. ABSTRACT Articular

Supramolecular Assembly of Stepped‐Persistent ROS Nanogenerator for Sustained Tumor Immunotherapy

Advanced Science, EarlyView.
ROS catalytic systems often fail to achieve both effective tumor elimination and persistent immune activation due to their monotonous ROS production profiles. A stepped‐persistent ROS nanogenerator was developed by supramolecularly assembling multiple ROS generation modules within a nanofiber structure to simultaneously extend ROS generation duration ...
