Multilayer microcapsules with a biconcave discoidal shape mimicking red blood cells (RBCs) are fabricated. The structure of the RBC-like microcapsules is verified by scanning electron and confocal laser scanning microscopies. The capsules show elastic deformation after being forced through a microcapillary with a smaller diameter, exhibiting a high recovery ratio of ≈90%. When the capsules are coated with hemoglobin (Hb),they are able to reversibly bind and release oxygen.
制备了具有模仿红细胞 (RBC) 双凹盘形的多层微胶囊。通过扫描电子显微镜和共聚焦激光扫描显微镜验证了 RBC 样微胶囊的结构。这些胶囊在被迫通过直径较小的微管后会发生弹性变形,表现出约 90%的高回复率。当胶囊表面覆盖血红蛋白 (Hb) 时,它们能够可逆地结合和释放氧气。
