A novel approach is developed for the metallization of DNA scaffolds based on the initial slow precipitation of palladium oxide onto DNA strands, followed by reduction with an appropriate reducing agent. The slow precipitation approach enables thin and continuous coatings to be formed on the DNA strands, as illustrated in the figure, with negligible parasitic metallization of the remaining surface.
