(a) AFM height images of immobilized bare DNA origami sheets and (b) a high magnification AFM image of an individual nanosheet (green box in a)) on a \(\mathrm {SiO_2}\) surface. (c) AuNPs attached to DNA origami at specific positions with high attachment yield and (d) high magnification AFM image of an individual AuNP decorated nanosheet (green box in c)). Inset figures show a cross-sectional profile of the individual origami and AuNPs decorated origami in b) and d), respectively. Green arrows indicate scan direction. (e) Measured attachment probabilities of AuNPs obtained from collected AFM images (histograms) and expected binomial distributions (solid lines) for two experimental conditions. The average attachment probabilities of AuNPs site occupation, p, are given for each case. (f) SEM images of two typical C-shape nanowires before and after being contacted by Au electrodes. Scale bars in in SEM images are \({250}\hbox { nm}\) and \({100}\hbox { nm}\) before and after gold contacts, respectively.
