Patterning of Gold Nanoparticles on DNA Self-Assembled Scaffolds
Figure 3
The 2D DNA template and the derivative 2D gold NP array. (a) The pathway of
2D gold NP array from the 2D DNA scaffold. The yellow dots
denote streptavidin labeled NPs to be anchored at the center of each tile motif
by the binding between biotin and streptavidin. (b) The AFM image of the 2D DNA scaffold. (c), (d) The
TEM images of the 2D gold NP arrays. The scale bar of (c) is 50
nm and the scale bar of (d) is 20 nm.
