Polyzwitterionic Organohydrogel and Soft Composite with Tunable Sol–Gel Properties Enabling On‐Demand Functionalization with Colloids

Advanced Science, EarlyView.
Poly[2‐(methacryloyloxy)ethyl]dimethyl‐(3‐sulfopropyl)ammonium hydroxide‐based organohydrogels are formed via nonsolvent‐induced gelation, featuring tunable viscoelasticity. Functional fillers (MXene nanosheets, magnetic NdFeB microparticles) enable electrical, magnetic, and mechanical responsiveness for applications in mechano‐tunable electromagnetic ...

Microgel‐Based Hierarchical Porous Hydrogel Patch with Adhesion and Resilience for Myocardial Infarction

Advanced Science, EarlyView.
This study develops a hierarchically porous hydrogel patch strategy (HPMP), based on gas‐shearing microfluidics and an aqueous two‐phase system to fabricate porous microgels as microgel‐based bioinks. The porous microgels with controllable porous structure exhibit excellent cellular behavior.
