The miniaturization and retained full shape‐memory functionality with particle switching to different predefined shapes is reported for semi‐crystalline multiblock copolymer matrices with all dimensions in the low micrometer‐range. A matrix size‐induced reduction of crystallinity suggests limitations of functionality in the low nanometer range. Applications as actuators in microdevices or as microcarriers with switchable shapes for modulated biorecognition are suggested.
