Summary: Polyacrylic acid (PAA) and its derivatives are commonly used as matrices in wound dressings, but their weak wet adhesion limits their clinical application. In this study, a PAA-based coacervate hydrogel with strong wet adhesion capability is created by mixing PAA copolymers with isoprenyl oxy poly(ethylene glycol) ether and tannic acid. The coacervate exhibits solid adhesion to both dry and wet substrates, with an adhesive strength to skin of 23.4 kPa and 70% adhesion underwater. It also possesses desirable self-healing and extensible properties, making it suitable for joints that undergo frequent movement. The coacervate demonstrates antibacterial activity, facilitates fibroblast migration, modulates macrophage polarization, shortens hemostatic time, and promotes collagen deposition, angiogenesis, and epithelialization, suggesting its promising potential as a wound dressing in medical translation.

Summary: In this study, a novel bioactive dressing based on native nondestructive sericin was developed. The dressing was directly secreted by silkworms through regulating their spinning behaviors. It possessed natural structures and bioactivities, as well as a porous fibrous network structure with high air permeability. Furthermore, the dressing showed pH-responsive degradability, softness, super absorbency, and high mechanical strength. It also supported cell viability, proliferation, and migration, and significantly accelerated the healing process in a mouse full-thickness skin wound model. These findings suggest that the sericin wound dressing has promising application and commercial value in wound repair.

Summary: Tannic acid (TA) has been traditionally used for treating traumatic bleeding in China and has been shown to accelerate wound healing in rats. This study aims to uncover the mechanism behind TA's promotion of wound healing. Results show that TA enhances macrophage growth and inhibits the release of inflammatory cytokines by inhibiting the NF-κB/JNK pathway. TA also activates the Erk1/2 pathway, leading to increased expressions of growth factors and promoted fibroblast migration. Additionally, TA stimulates macrophages to secrete exosomes enriched in miR-221-3p, which enter fibroblasts and bind to the CDKN1b gene, promoting fibroblast migration. This study provides new insights into TA's acceleration of wound healing in the inflammatory and proliferative phases.

Summary: Developing an antibiotic-free wound dressing with effective hemostasis and antibacterial and antioxidant capacity is highly desirable. In this work, a three-dimensional chitosan/polyvinyl alcohol-tannic acid porous nanofiber sponge (3D-TA) was prepared via electrospinning. The 3D-TA sponge, with its unique fluffy structure, exhibited high porosity, water absorption and retention ability, as well as hemostatic capacity. Moreover, the 3D-TA sponge functionalized by tannic acid showed high antibacterial and antioxidant capacity without the need for antibiotics. The in vivo experiment demonstrated that the 3D-TA sponge could accelerate wound healing. These newly developed 3D-TA sponges hold great potential as wound dressings for future clinical application.

Summary: This study reports a coacervate-to-hydrogel strategy to enhance the water repulsion and adhesion ability of bioadhesives. The deposition of polyethyleneimine/thioctic acid (PEI/TA) coacervate onto underwater substrates effectively repels interfacial water and transforms into a hydrogel within minutes, resulting in enhanced adhesion. The coacervate-to-hydrogel strategy has the advantages of adaptability, strong interfacial adhesion, and robust bulk adhesion, showing potential for diverse biomedical applications.
