| Abstract: | Synthetic DNA has emerged as a powerful self‐assembled material for the engineering of nanoscale supramolecular devices and materials. Recently dissipative self‐assembly of DNA‐based supramolecular structures has emerged as a novel approach providing access to a new class of kinetically controlled DNA materials with unprecedented life‐like properties. So far, dissipative control has been achieved using DNA‐recognizing enzymes as energy dissipating units. Although highly efficient, enzymes pose limits in terms of long‐term stability and inhibition of enzyme activity by waste products. Herein, we provide the first example of kinetically controlled DNA nanostructures in which energy dissipation is achieved through a non‐enzymatic chemical reaction. More specifically, inspired by redox signalling, we employ redox cycles of disulfide‐bond formation/breakage to kinetically control the assembly and disassembly of tubular DNA nanostructures in a highly controllable and reversible fashion. |
