The refolding efficiencies of different DNA origami purified structures. The individual shapes of the structures were observed with atomic force microscopy (AFM), and the quality was judged according to three stages (well-folded, folded, and no structure). (a) truss origami. (b) The conventional origami structure. In bulk solution, the refolding efficiency of the truss structure was higher than that of the conventional origami. In the microcompartment droplet, over 20% of the refolded truss structure was observed, even under the “Quick_1min” annealing conditions.
