Fig. 7: 4-state ring-to-ring reconfiguration based on C-shape TC tiles.

a Schematics of the one-to-one reconfiguration process between four rings, through a total of 12 paths. The four nanorings are Ring 1 (N = 25), Ring 2 (N = 8), Ring 3 (N = 8), and Ring 4 (N = 5). Each path is labeled with a number from (1) to (12), and the arrow shows the reconfigured direction. The Monomer tile is marked with yellow. Green color represents the toehold-mediated strand displacement functional domain. b The AFM images of each nanoring and the reconfiguration product. The first row presents the Ring 1 and its reconfiguration products through path 1, path 2, and path 3, from left to right, respectively. Similarly, the last three rows depict Ring 2, Ring 3, and Ring 4 and the corresponding three paths of reconfigured nanorings, from top to bottom, respectively. The yield counting information is inserted on top of the AFM images. In the yield analysis graphs, the bars for nanorings with N-1, N, N + 1, and other monomers are marked with light blue, yellow, red, and green color, respectively. The information of invader and setting strands of each transition is summarized in Supplementary Table 13. Image size: 1 μm × 1 μm, scale bar: 200 nm. Source data are provided as a Source Data file.
