Blooming block copolymers! Uniform droplets of solvent that contain amphiphilic polystyrene–poly(ethylene oxide) diblock copolymers are prepared using a microcapillary device. Solvent removal drives interfacial instabilities, through which the polymer assembles into complex hierarchical microparticle structures (see picture).
