Wet, wet, wet : A responsive surface is presented that can switch between stable superhydrophilic, metastable superhydrophobic, and stable superhydrophobic states by an enthalpy‐driven process (see picture). This macroscopic phenomenon of surface wettability originates from the coordinative effect of the collective nanoscale motion of DNA nanodevices and the surface microstructure.
