Recent years have witnessed substantial advices in the use of DNA as a smart material to construct periodically patterned structure. Here we reports the synthesis of conductive metal nanowires by using aligned and immobilized DNA strands on solid substrates. The method combines molecular combing and Transfer printing, taking benefits from both. Therefore, DNA localization has been achieved by moving air-water interface. In addition, oxidized aniline-capped Au nanoparticles prepared and employed for metallization of DNA molecules and improving their conductivity. This approach is broadly applicable to large-scale DNA integration and practical production of nanowires, as it does not need any surface modification or special equipment. This method may provide a simple way to studying nanoscale electronics.
