角蛋白在生物材料中的应用

Application of Keratins in Biomaterials

结合角蛋白自身特殊的结构及其性能,介绍了角蛋白的提取方法,如机械法、酸碱法、还原法、氧化法和金属盐法等;重点综述了角蛋白及其改性产品在生物材料中的应用,如角蛋白可以作为骨折内固定棒、人工腱、烧伤敷料、注射生物复合填充材料等;最后展望了角蛋白的应用前景和发展方向。

Combining with the special structure and properties of keratin, the extraction methods of keratin are introduced, such as the mechanical method, acid-base method, reduction, oxidation and metal salts, etc. The applica- tion of keratin and modified products in the field of biological materials are emphatically reviewed. For example, the keratin is produced for fracture fixation rods, artificial tendons, burn dressings and injectable bio-composite filling ma- terials. Finally, the prospects and development direction of the keratin are prospected.
