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.

Particles, including nanoparticles and microparticles, and pharmaceutical formulations thereof, containing conjugates of an active agent such as a therapeutic, prophylactic, or diagnostic agent attached to a targeting moiety via a linker have been designed which can provide improved temporospatial delivery of the active agent and/or improved biodistribution. Methods of making the conjugates, the particles, and the formulations thereof are provided. Methods of administering the formulations to a subject in need thereof are provided, for example, to treat or prevent cancer or infectious diseases.
The preparation of poly-2-oxazoline amphiphilic polymers and copolymers is described. Self-assembled particles comprising these amphiphilic polymers and which are useful for the targeted delivery of therapeutic and diagnostic agents are also described.
