A novel multifunctional, proton‐fueled DNA nano‐spring has been constructed. By incorporation of the G‐quadruplex/i‐motif sequence into the assembly, the nanodevice can perform spring‐like motions in response to changes in the environmental pH without permanent deformation. Nanosized objects/functional groups could be assembled/disassembled into this system in an addressable, contractile, and reversible manner.
