Figure 3. Purified and salt-free 2D DNA origami nanostructures deposited onto the untreated silicon substrates using a spray-coating technique.

Figure 3

AFM images of (a) Seeman tile (ST) and (b) double-triangle (DT) coated substrates. The scale bars are 1 μm. (c,d) Zoomed-in images of single objects. The scale bars are 100 nm. (e,f) Histograms of the nearest-neighbour distances for deposited ST and DT origami shapes. The deposition was carried out using optimised parameters for homogeneous coating.
