Cohesion Regulation of Polyphenol Cross‐Linked Hydrogel Adhesives: From Intrinsic Cross‐Link to Designs of Temporal Responsiveness

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Oct. 25, 2024

Abstract Polyphenol hydrogels have found widespread application in wound healing, bone repair, drug delivery, and biosensors due to their robust wet adhesion, high ductility, excellent self‐healing ability. However, these often exhibit low intrinsic cohesion, which limits overall adhesive strength. Enhancing cohesion is critical for improving both the adhesion mechanical properties of hydrogels, thereby expanding utility biomedical fields. This review begins by exploring strategies enhance polyphenol hydrogel adhesives, detailing modifications that act individually or synergistically. The importance temporally regulating emphasized accommodate various applications environmental conditions. Finally, this paper discusses remaining challenges regulation outlines prospects future research. It hoped comprehensive will provide new insights into development advanced polyphenolic adhesives contribute design “smart adhesives” increasingly complex needs applications.

Guiding the Path to Healing: CuO₂‐Laden Nanocomposite Membrane for Diabetic Wound Treatment

Small, Journal Year: 2023, Volume and Issue: 20(3)

Published: Sept. 8, 2023

Abstract Diabetic chronic wounds pose significant clinical challenges due to their characteristic features of impaired extracellular matrix (ECM) function, diminished angiogenesis, inflammation, and increased susceptibility infection. To tackle these provide a comprehensive therapeutic approach for diabetic wounds, the first coaxial electrospun nanocomposite membrane is developed that incorporates multifunctional copper peroxide nanoparticles ( n ‐CuO 2 ). The membrane's nanofiber possesses unique “core/sheath” structure consisting +PVP (Polyvinylpyrrolidone)/PCL (Polycaprolactone) composite sheath PCL core. When exposed wound's moist environment, PVP within gradually disintegrates, releasing embedded . Under weakly acidic microenvironment (typically infected wounds), decomposes release H O Cu 2+ ions subsequently produce ·OH through chemodynamic reactions. This enables anti‐bacterial activity mediated by reactive oxygen species (ROS), suppressing inflammation while enhancing angiogenesis. At same time, dissolution unveils nano‐grooved surface patterns on nanofibers, providing desirable cell‐guiding function required accelerated skin regeneration. Through meticulous material selection design, this study pioneers development functional nanocomposites multi‐modal wound therapy, which holds great promise in guiding path healing wounds.
