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

Figure 2

CD spectra of (a) duplex I, (b) duplex II, and (c) duplex V in the absence or presence of Ag(I) (black: no Ag(I); red: 1 equiv. of Ag(I); blue: 1.5 equiv. of Ag(I)). The CD spectra of duplexes III and IV including 2-methylimidazole rather than imidazole are essentially the same [35, 37] and are therefore not shown. In (c), a different color code applies (red: 4 Ag(I) per duplex; blue: 6 Ag(I) per duplex).
