Figure 1
Schematic showing the process of DNA tile directed self-assembly of QD arrays.
Figure 2
Figure 2
a) From left to right: AFM images of DX-ABCD array alone with each A tile bearing a biotin; the biotinylated DX-ABCD array incubated with STV-QD conjugate; and same array incubated with streptavidin only; b) Cross section analysis of the AFM images. Each trace corresponds to the same colored arrow in a).
