Synthesis of metallic nanowire networks on DNA

Biomolecular structures with their self-assembly capability may provide new opportunities for the packaging of electronic devices of molecular size. On the way towards DNA-based nanoelectronics we show novel approaches for two major process steps: the construction of defined DNA interconnects and the transition of these networks into metallic nanowires. To this aim, we show controlled incorporation of functionalized DNA molecules into defined sites of contact arrays by application of hydrodynamic flow and their metallization by a photo-induced reduction process resulting in chains of platinum clusters.
