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 springlike 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.
