DNA origami sheet based C-shaped conducting nanowires

Small DNA origami templates 90 nm x 70 nm DNA origami nanosheets with three functionalized sides holding a total of eight capture strands for decoration with gold nanoparticles were fabricated. Electroless gold growth is applied to selectively grow the gold nanoparticles until they merge into continuous nanowires. Finally, this work demonstrates the application of shape-controlled C-shaped gold wires as precisely tailored metal contacts to single, isolated nanowires to better understand the charge transport characteristics at different temperatures.
