Fig. 6: Single-stranded tiles (SST) for precise nanorings and their reconfiguration.

Schematics and AFM images, a 6-monomer nanorings assembled from annealing, intermediate ladders, and transformed 18-monomer nanorings; b 18-monomer nanorings assembled from annealing, intermediate ladders, and transformed 6-monomer nanorings. The SST nanorings contain six C-shape monomer tiles with different sequences, while the big nanoring contains three times the monomers present in the small nanoring. The six monomers are labeled with six different colors. Green color represents the toehold-mediated strand displacement functional domain. The assembly yield of each sample is labeled on corresponding AFM images. The formation yield is calculated based on the exact N value (see section 1 Methods of the Supplementary Information). The dashed arrows point out the SDR reaction domain. The zoom-in AFM images are cropped from the corresponding images in this figure. Source data are provided as a Source Data file.
