Figure 5

(a) Schematic. Three identical ~400-nm long DNA nanorods are linked to the outer edge of a DNA ring with diameter of ~60 nm through the hybridization between staple extensions (inset). The ring and the end of the rod are labeled with Cy3 (green) and Cy5 (red), respectively. (b) A representative TIRF microscopy image. Scale bar: 5 μm.
