A simple strategy to fabricate stimulus‐responsive patterned PNIPAAM‐brush microstructures (‘anemones’) is presented. The size of the microstructures can be adjusted by setting the composition of thiol and the contact pressure. We demonstrate that the patterned PNIPAAM‐brush microstructures have a triggerable and reversible conformation transition, and can potentially be used as microcontainers to reversibly dock and release microparticles.
