Due to their complex behavior, Janus particles became a highly attractive research topic. Particularly, interesting groups of Janus particles are the ones that are sensitive to external signals such as change of temperature, pH, light, etc. These Janus particles are able to dynamically assemble/disassemble to forming very complex structures or reversibly/irreversibly change their shape by folding/bending. Recent progress in this fascinating field is discussed.
