葡聚糖-活性酯Dextran-NHS  是一款来自燕麦，蘑菇和酵母的葡聚糖衍生物，由于其优异的药理学性质，防腐，促进伤口愈合性能，粘合能力等，已在医学领域广泛用于水凝胶，药物递送和止血材料。通过改性葡聚糖（特别是聚葡聚糖醛（PDA））和具有氨基的聚合物或小分子的化学或物理组装制备的生物水凝胶材料（如抗菌剂，伤口愈合敷料，抗粘附产品等）已被广泛研究。

Dextran active ester dextran NHS is a dextran derivative from oats, mushrooms and yeast. Due to its excellent pharmacological properties, antiseptic, wound healing promoting performance, adhesive ability, etc., it has been widely used in the medical field for hydrogels, drug delivery and hemostatic materials. Biological hydrogel materials (such as antibacterial agents, wound healing dressings, anti adhesion products, etc.) prepared by chemical or physical assembly of modified dextran (especially polydextran aldehyde (PDA)) and polymers or small molecules with amino groups have been widely studied.

Dextran葡聚糖（右旋糖酐Dextran），是一类具支链葡萄糖高聚物，他不带电荷，呈电中性，易溶于水，葡聚糖跟PEG一样具有良好的生物相容性，毒性较低适用于动物体内，葡聚糖还是一种生物可降解高分子聚合物，它可降解为低分子的糖。
