Progress in Application of Carrageenan Hydrogel in Biomedicine

Abstract

Carrageenan-based hydrogel, as a kind of natural polymer soft material with a threedimensional network structure, has good biocompatibility, biodegradability and biosafety, and has high water content, structure and performance. The matrix is similar and has received extensive attention from researchers. This article outlines the structure and properties of carrageenan-based hydrogels, and classifies carrageenan-based hydrogels according to their functionality, focusing on self-healing, antibacterial, stimulus-responsive, and conductive carrageenan-based hydrogels. The characteristics and properties of glue and its application progress in drug delivery, wound healing, tissue engineering, and biological intelligent sensing. Finally, the problems and challenges faced by carrageenan-based hydrogels are discussed, and the future of carrageenan-based hydrogels are prospected. Possible development trend.
