摘要：

We report a one-step method of assembling supramolecular colloidosomes at the interface of microfluidic droplets. The self-assembly process utilises a versatile CB[8] host-guest system to reversibly crosslink polystyrene nanoparticles via a polyacrylamide linker. These micrometresized hollow structures can be loaded with water-soluble cargo during formation, which can then undergo triggered release.
