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

Figure 4

Fluorescence spectra of (a) duplex I and (b) duplex II upon excitation at 330 nm (blue: in the absence of Ag(I); black: in the presence of 1 equiv. of Ag(I); red: after reduction by NaBH₄). The weak intensity indicates that the samples are essentially nonfluorescent.
