A team of researchers at Karlsruhe Institute of Technology (KIT) and Heidelberg University have recently introduced functional 3-D hetero-microstructures based on Poly (N-isopropylacrylamide) (pNIPAM) a polymer that responds to changes in temperature close to its lower critical solution temperature. Stimuli-responsive microstructures are of key importance for the creation of adaptable systems, which can have interesting…
