Size-Controllable DNA Rings with Copper-Ion Modification

Cu2+‐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 Cu2+ modification, and the results provide clear evidence for the co‐ordination of Cu2+ in DNA str...

Description
Summary:Cu2+‐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 Cu2+ modification, and the results provide clear evidence for the co‐ordination of Cu2+ in DNA structures.
