Preventing bacterial infections and accelerating wound closure are essential in the process of healing. Current dressings lack enough mechanical properties, self-healing ability, tissue adhesiveness, killing also relies on use antibiotic drugs. Herein, a well-designed hybrid hydrogel dressing is constructed by simple copolymerization acrylamide (AM), 3-acrylamido phenylboronic acid (AAPBA), chitosan (CS), nanoscale tannic (TA)/ferric ion (Fe3+) complex (TFe). The resulting possesses lots free catechol, acid, amine, hydroxyl groups contains many reversible dynamic bonds such as multiple hydrogen boronate ester bonds, thereby showing satisfactory fast desirable tissue-adhesive performance. Benefiting from high photothermal conversion efficiency TFe, exhibits antibacterial activity against both Gram-positive Gram-negative bacteria. Moreover, embedded TFe endows with good antioxidant activity, anti-inflammatory property, cell proliferation to promote regeneration. Remarkably, vivo animal assays reveal that effectively eliminates biofilm bacteria sites accelerates healing infected wounds. Taken together, developed versatile hydrogels overcome shortcomings traditional expected become potential for future biomedical applications.

Wearable sensors made of flexible and stretchable hydrogels have garnered significant attention. However, their use has been limited by poor mechanical performance, such as toughness, self-recovery, a large response–recovery time. To overcome these limitations, we developed novel cross-linking agent-based hydrogel with high stretchability, antifatigue properties, good conductivity. These were introducing l-glutamic acid (LGA) into hydrophobically cross-linked polyacrylamide (PAmm) chains. In this system, LGA dynamically the micelle–micelle micelle–polymer chains greatly regulates properties hydrogels. The noncovalent synergistic interactions that came insertion enable to achieve stretchability stress values, fast self-recovery behaviors without help foreign stimuli. Additionally, LGA-based can function durable highly sensitive strain for detecting various deformations time gauge factor value. As result, capability be designed wearable are capable human joint motions, neck twisting, bending, wrist, finger, elbow movements. Similarly, monitoring different subtle motions speaking differentiating between words, swallowing, drinking through larynx vibrations. Besides ability differentiate reproduce written words reliability. LGA-regulated potential applications in electric skins, medical monitoring, soft robotics, touch panels.
