Cu 2+-modified DNA nanostructures are investigated using differently sized DNA rings that are composed of core and extension motifs. Chemical reduction and current measurements are adopted for verifying Cu 2+ modification, and the results provide clear evidence for the co-ordination of Cu 2+ in DNA structures.
