Supramolecular colloidosomes: fabrication, characterisation and triggered release of cargo

Abstract

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 micrometre-sized hollow structures can be loaded with water-soluble cargo during formation, which can then undergo triggered release.
