Summary: A photoactive self-healing hydrogel called Macropatch has been developed to promote wound healing by protecting the wound from further injury, sealing organ bleeding, and preventing bacterial infections under visible light irradiation. The hydrogel exhibits good self-healing capability, mechanical strength, tissue adhesiveness, and visible light-induced antibacterial activity, leading to a fast recovery of bacteria-infected wounds.

Summary: Tea tree oil (TTO) is encapsulated into the hydrogel network via a previous emulsification process, and a tough and antibacterial injectable hydrogel is synthesized by the Schiff base reaction between carboxymethyl chitosan (CMCS) and genipin (GP). The obtained hydrogels exhibit high adhesive strength (about 162.75 kPa), excellent antibacterial properties (over 90%), and great biocompatibility. The heterogeneous hydrogel shows good slow-release properties of TTO for accelerated healing of complex anal fistula wounds according to an anal fistula-like wound healing experiment.

Summary: The present study developed a L-proline conjugated chitosan scaffold for wound healing. The scaffold was characterized by various tests and showed no cytotoxicity. In vitro experiments demonstrated that the modified scaffold promoted wound closure and collagen deposition. These findings suggest that the L-proline conjugated scaffold has potential as a wound dressing to improve wound healing.

Summary: The BP/CS-bFGF hydrogel dressing prepared in this study shows great potential for diabetic chronic wound management. It has strong wet-tissue adhesion, self-mending, and antibacterial properties, and displays fast hemostasis capacity. The hydrogel dressing significantly accelerates full-thickness diabetic wound repair by increasing the production of Ki67, promoting the generation of epithelialization and collagen, inducing the formation of hair follicles, and enhancing neovascularization.

Summary: An electroactive hydrogel was constructed by rapidly forming dynamic imine bonds between oxidized sodium alginate (OSA) and carboxymethyl chitosan (CMCS), and in situ forming silver nanoparticles (AgNPs) by UV irradiation. The hydrogel exhibited injectability, self-healing ability, biocompatibility, and antibacterial activities. It promoted cell proliferation and accelerated wound healing in a skin defect model.

Summary: A series of multifunctional carboxymethyl chitosan (CMCS)-based hydrogels were fabricated using a facile urate oxidase (UOX)-horseradish peroxidase (HRP) cascade enzymatic crosslinking system, which can accelerate wound healing due to the retained enzymatic activity. These hydrogels exhibit excellent antioxidant performance and enhanced antibacterial capacity, effectively promoting skin wound repair by reducing oxidative stress, relieving inflammation, promoting collagen deposition and upregulating the expression level of CD31.

Summary: Hydrogels formed from CMCS biopolymer via electron beam irradiation were evaluated for their potential in wound healing therapy. The hydrogel supported healing and showed positive effects on inflammatory infiltration, collagen formation, and epidermalization. The use of competitive radiation technology for synthesis allowed for the product to be sterilized during synthesis.

Summary: Composite chitosan-collagen nanofibrous mats embedded with curcumin were prepared by electrospinning and showed superior biological activity as wound-healing patches. A mild crosslinking protocol was developed to ensure stability without affecting biocompatibility. The composite patches had a porous nanostructure, thermal stability, mechanical features, and water-related properties suitable for wound healing. Curcumin release was sustained for 72 hours, providing prolonged bioactivity and antioxidant properties. The combination of chitosan, collagen, and curcumin promoted cell adhesion, proliferation, and antibacterial capabilities.
