The present invention relates to a method for preparation of monodisperse cell-targeting giant unilamellar vesicles based on symmetrically division of a parent polymer shell-stabilized giant unilamellar vesicle into smaller polymer shell-stabilized giant unilamellar vesicles with a diameter smaller than 10 µm using a microfluidic splitting device.
The inventive method allows preparation of differently charged giant unilamellar vesicles as well as bioligand- and PEG-conjugated giant unilamellar vesicles, which are useful for targeted cellular delivery at high efficiency and specificity. A further advantage of the present invention is that the giant unilamellar vesicles can deliver huge cargos such as drug releasing porous microparticles, high amounts of in vivo imaging probes, viruses, or up-and-coming DNA origami robots.
本发明涉及一种制备单分散细胞靶向巨型单拉美米尔囊泡的方法,其基础是利用微流体分割装置将母体聚合物壳稳定巨型单拉美米尔囊泡对称分割成直径小于10微米的较小聚合物壳稳定巨型单拉美米尔囊泡。
本发明的方法可制备不同电荷的巨型单拉米分子囊泡以及生物配体和 PEG 共轭巨型单拉米分子囊泡,这些囊泡可用于高效、特异性的细胞靶向递送。本发明的另一个优点是,巨型单拉美拉尔囊泡可以输送巨大的载体,如释放药物的多孔微颗粒、大量的体内成像探针、病毒或新兴的 DNA 折纸机器人。
