Here we investigate self-assembled devices using DNA as excellent constructive and self-organizing material for nanoelectronics. So-called DNA origamis have been used as molds to build metallic nanowires in any shape and size, in contact with double stranded (ds) DNA segments. The combination with electron beam lithography as top down process allows for attaching metallic wires to the DNA origamis of smallest dimensions.
We investigate the charge transport through self-assembled, DNA templated metallic nanowire- ds-DNA- metallic nanowire structures. The ds-DNA structures between the Au nanowires are about 15 nm long (~30bp). We characterize the charge transport through these structures by current-voltage measurements. This electrical measurement through ds-DNA demonstrate the feasibility to use DNA for electron transport in nanodevices (Molecular electronics) and also increase the potential to use this bio- molecule for future applications.
