Reversible disruption and regeneration of block‐copolymer micelles has been achieved by UV and visible‐light irradiation and studied by atomic force microscopy (see picture). A hydrophobic dye encapsulated in the original polymeric micelles was released after UV irradiation. Remarkably, some of the released hydrophobic dye was re‐encapsulated on regeneration of the micelles by irradiation with visible light.
