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 between 1 µm and 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大单层泡囊的方法,该方法基于将母体聚合物壳稳定的巨大单层泡囊对称分裂成直径在1微米至10微米之间的较小聚合物壳稳定的巨大单层泡囊,使用微流体分裂装置。这种创新的方法允许制备带有不同电荷的巨大单层泡囊,以及生物配体和PEG共轭的巨大单层泡囊,这对于高效和特异性的靶向细胞传递非常有用。本发明的另一个优点是,巨大单层泡囊可以传递大量的货物,例如释放药物的多孔微粒、大量体内成像探针、病毒或即将推出的DNA折纸机器人。
