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

الملخص EN

A series of DNA double helices containing different numbers of silver(I)-mediated base pairs involving the artificial nucleobases imidazole or 2-methylimidazole has been applied for the generation of DNA-templated silver nanoclusters.

The original Ag(I)-containing nucleic acids as well as the resulting nanoclusters and nanoparticles have been characterized by means of UV/Vis spectroscopy, circular dichroism (CD) spectroscopy, fluorescence spectroscopy, and transmission electron microscopy (TEM).

The results show for the first time that metal-mediated base pairs can be used for the templated growth of metal nanoclusters.
