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

Table 2

Melting temperatures /°C of the duplexes in the absence and presence of Ag(I).

	0 equivalent of Ag(I)	1 equivalent of Ag(I)	(0 → 1 equivalent of Ag(I))
Duplex I	30.6	51.1	20.5
Duplex II	29.5	52.2	22.7
Duplex III	32.8	60.8	28.0
Duplex IV	30.7	60.7	30.0
Duplex V	52.4	58.4	6.0

Conditions: 2 M duplex, 150 mM NaClO₄, and 5 mM MOPS (pH 6.8). Four Ag(I) were added to the duplex.
