一般說明

海藻酸钠是一种胶凝和无毒的阴离子多糖。 海藻酸链上的羧酸基团使其不溶于水。然而,将海藻酸转化为钠盐形式,将使其易溶于水。[1]

應用

海藻酸钠被用于:
  • 与壳聚糖组合用于制造骨组织工程的可生物降解型多孔支架。[2]
  • 研究改性两亲性藻酸盐衍生物的特性[3]
  • 利用 体外 消化模型研究藻酸盐对脂质消化速率的影响[4]
  • 制备藻酸盐水凝胶[5]
  • 作为β-半乳糖苷酶微粒的包封剂[6]

文章

Chitosan is a naturally occurring polysaccharide ideally suited for use in medical supplies, devices, therapeutics, and diagnostics. The unique natural characteristics of chitosan include its cationic, biocompatible, biodegradable, non-toxic, non-immunogenic, and antimicrobial properties.

Collagen molecules play a critical role in tissue architecture and strength, and in cell-matrix interactions as insoluble ligands to regulate the diverse phenotypic activities of cells.

Hydrogel-based biomaterials for cell delivery and tissue regeneration applications are discussed.
