Figure 3.

Square, hexagonal and diamond shaped DNA origami staple tiles assembled into super-structures using the design strategy depicted in Figure 2. (a), (b) Design and AFM images, respectively, of 3 × 3 square staple tiles assembled into a super-structure. The length of each side of the individual square tiles is 73 nm; the length of each side of the super- structure is 240 nm. (c), (d) Design and AFM images, respectively, of 3 × 3 hexagonal staple tiles assembled into a super-structure. The length of each side of the hexagonal tiles is 53 nm; the length of each side of the super-structure is 285 nm. (e), (f) Design and AFM images, respectively, for mixed hexagonal and diamond staple tiles assembled into a super-structure. The length of each side of the diamond tiles is 53 nm; the dimensions of the super-structure are 220 nm × 375 nm. (scale bars:200 nm)
