We build hierarchical DNA origami fibrils using protonated DNA strands. By employing a small molecule that releases protons during irradiation, our system is activated by light and is assembled under dissipative conditions. Generating no waste, our fibrils can be built and demolished multiple times, underscoring the utility of pH-responsive, non-canonical DNA motifs for out-of-equilibrium assembly.
