Figure 5

(a) Projected potential of a DNA snippet connecting two gold NPs on a single layer of graphene substrate, and (b) corresponding atomistic three-dimensional model. Scale bar, 2 nm. Images were generated from scanning over the area enclosed in the green box using (c–e) BF-STEM, (f–h) ADF-STEM and (i–k) MIDI–STEM at infinite and two low electron doses. Conventional STEM probes were used for BF- and ADF-STEM, while 20 ring pairs were used for MIDI–STEM.
