An Ag-functionalized structural color hydrogel (Ag-SCH) sensor is constructed for colorimetric detection of glutathione (GSH). The hydrogel is prepared by using the coordination of Ag and 1-vinylimidazole (1-VI) as cross-linking network. GSH acts as a competitive ligand to break the coordination between Ag and 1-VI, leading to the expansion and structural color change of the hydrogel.

Smart hydrogels have advanced rapidly in recent years. However, systems responsive to a single stimulus are typically triggered by specific cues, limiting their adaptability in complex and dynamic biological environments. To overcome this limitation, this study developed a dual-responsive hydrogel sensitive to both temperature and mechanical stress.

Extensive peripheral nerve injuries often lead to the loss of neurological function due to slow regeneration and limited recovery over large gaps. Current clinical interventions, such as nerve guidance conduits (NGCs), face challenges in creating biomimetic microenvironments that effectively support nerve repair. The developed GrooveNeuroTube is composed of hyaluronic acid methacrylate and gelatin methacrylate hydrogel, incorporating active agents (growth factors and antibacterial agents) encapsulated within an NGC conduit made of 3D-printed PCL grid fibers.

Developing high-performance wearable flexible sensors that can adapt well to complex environments has become a hotspot. Herein, a polyvinyl alcohol based composite hydrogel sensor with high mechanical strength, desirable frost/swelling resistance, and highly sensitive sensing performance was proposed by a multi-component collaborative design strategy. Meanwhile, an intelligent gesture recognition system was established by combining machine learning algorithm.

High-performance hydrogel biomaterials hold considerable promise for advanced wound care. However, the suboptimal mechanical properties of conventional hydrogel materials limit their practical application. In this study, Hyaluronic acid sodium salt (HA), xanthan gum (XG), and N-acryloyl-glycinamide (NAGA) hydrogels with porous structures were successfully fabricated using in-situ extrusion 3D printing technology, and a functionalization strategy involving tea polyphenol (TP) immersion was proposed to enhance material properties through additional hydrogen bonding.
