Alginate is a natural polysaccharide exhibiting excellent biocompatibility and biodegradability, having many different applications in the field of biomedicine. Alginate is readily processable for applicable three-dimensional scaffolding materials such as hydrogels, microspheres, microcapsules, sponges, foams and fibers. Alginate-based biomaterials can be utilized as drug delivery systems and cell carriers for tissue engineering. Alginate can be easily modified via chemical and physical reactions to obtain derivatives having various structures, properties, functions and applications. Tuning the structure and properties such as biodegradability, mechanical strength, gelation property and cell affinity can be achieved through combination with other biomaterials, immobilization of specific ligands such as peptide and sugar molecules, and physical or chemical crosslinking. This review focuses on recent advances in the use of alginate and its derivatives in the field of biomedical applications, including wound healing, cartilage repair, bone regeneration and drug delivery, which have potential in tissue regeneration applications.
藻酸盐是一种天然多糖，具有优异的生物相容性和生物降解性，在生物医学领域有许多不同的应用。藻酸盐易于加工成适用的三维支架材料，如水凝胶、微球、微胶囊、海绵、泡沫和纤维。基于藻酸盐的生物材料可用作药物递送系统和组织工程的细胞载体。藻酸盐可通过化学和物理反应轻松改性，以获得具有各种结构、性质、功能和应用的衍生物。通过与其他生物材料结合、固定特定配体（如肽和糖分子）以及物理或化学交联，可以调节其结构和性质，如生物降解性、机械强度、凝胶化性质和细胞亲和力。本综述重点关注藻酸盐及其衍生物在生物医学应用领域的最新进展，包括伤口愈合、软骨修复、骨再生和药物递送，这些在组织再生应用中具有潜力。
