The thermoreversible coil-globule transition of polymers at the lower critical demixing temperature is a popular theme in polymer chemistry. Here, this phenomenon is exploited to induce a reversible contraction/expansion by temperature changes in a membrane-achored N-isopropylacrylamide copolymer (shown schematically below). With this liposome-anchored “molecular accordion” the dynamics of the cytoskeleton of biological systems can be roughly simulated.
