A reactor for the synthesis of gold nanoparticles (see atomic force microscopy image) is one of the uses of a poly(styrene)‐ block ‐poly(2‐vinylpyridine)‐ block ‐poly(ethylene oxide) triblock copolymer (PS‐ b ‐P2VP‐ b ‐PEO) which forms core–shell–corona micelles in water. Very low polydispersity spherical micelles are observed that consist of a PS core surrounded by a pH‐sensitive P2VP shell and a corona of PEO chains end‐capped by a hydroxyl group. The corona can act as a site for attaching responsive or sensing molecules.
