DNA origami templates are known to exhibit many advantages to integrate functional components at desirable locations for nanoelectronics applications. In order to immobilize conducting or semiconducting species in a bottom-up approach, the programmed assembly of DNA templates is utmost necessary. This report demonstrates the conducting nanowires enabled bridging of two linear DNA origami (DO) nanostructures by utilizing the host-guest interaction of biotin-STV and sequence-specific silver metallization of poly(dG-dC) DNA nanowires. The enzymatic synthesis of bis-biotinylated poly(dG-dC), facile synthesis of biotin-STV and silver-nanowire bridged DNA templates were characterized by gel electrophoresis, atomic force microscope imaging techniques. The strategy utilized here provides a method that can precisely connect heterogeneous templates towards bottom-up fabrication of practical nanoelectronics.
