Bio‐Multifunctional Hydrogel Patches for Repairing Full‐Thickness Abdominal Wall Defects

Developing bio‐multifunctional patches with natural extracellular matrix‐like structures, excellent high adhesion in the wet state, self‐healing ability, antibacterial activity, and favorable cell responses for accelerating tissue healing is highly desirable in clinical applications. Herein, bio‐multifunctional composite hydrogels are developed by coupling carboxymethyl chitosan and 4‐arm poly (ethylene glycol) aldehyde for full‐thickness...
