Hydrogels were the first biomaterials designed for clinical use. Their discovery and applications as soft contact lenses and implants are presented. This early hydrogel research served as a foundation for the expansion of biomedical polymers research into new directions: design of stimuli sensitive hydrogels that abruptly change their properties upon application of an external stimulus (pH, temperature, solvent, electrical field, biorecognition) and hydrogels as carriers for the delivery of drugs, peptides, and proteins. Finally, pathways to self-assembly of block and graft copolymers into hydrogels of precise 3D structures are introduced.
水凝胶是最早设计用于临床的生物材料。文中介绍了它们作为软性隐形眼镜和植入物的发现及应用。早期的水凝胶研究为生物医学聚合物研究拓展到新方向奠定了基础:设计对刺激敏感的水凝胶,这类水凝胶在施加外部刺激(pH值、温度、溶剂、电场、生物识别)时会突然改变其性质;以及将水凝胶用作药物、肽和蛋白质递送的载体。最后,介绍了嵌段共聚物和接枝共聚物自组装成具有精确三维结构的水凝胶的途径。
