Formation of Silver Nanoclusters from a DNA Template Containing Ag(I)-Mediated Base Pairs

Figure 5

TEM bright-field images of silver nanoclusters and nanoparticles on a carbon film. Solutions of (a) duplex I, (b) duplex II, (c) duplex V, and (d) without nucleic acid in the presence of AgNO₃ after the reduction with NaBH₄ led to the shown images and corresponding histograms of the size distribution. Please note the different scale bars in (c) and (d).
