  公开（公告）日：2021-06-23

  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.

  The present invention relates to a method for producing synthetic extracellular vesicles comprising a lipid bilayer including at least two lipids, optionally one or more extracellular vesicle associated proteins, and optionally one or more nucleic acid molecules. The inventive synthetic extracellular vesicles are formed by emulsification using a mechanic emulsifier in the form of polymer shell stabilized synthetic extracellular vesicles. The inventive method allows producing synthetic extracellular vesicles miming the composition and function of natural extracellular vesicles. Therefore, synthetic extracellular vesicles with specific protein and nucleic acids compositions are also disclosed herein, as well as their therapeutic uses.
