DNA Origami takes advantage of base complementarity of individual short oligonucleotides, to fold a long scaffold strand into almost any continuous 2D or 3D shape. We recently introduced a new concept of DNA origami mold-based particle synthesis that allows the synthesis of inorganic nanoparticles with a programmable shape. We demonstrated the concept by fabricating a 40 nm long rod-like gold nanostructure with a quadratic cross-section. We expanded the capabilities of the mold-based particle synthesis to demonstrate the synthesis of uniform μm long conductive gold nanowires with 20-30 nm diameters. With conductance characterization, metallic conducting wires were demonstrated. Here the concept is further expanded by designing mold monomers with different geometries and interfaces. We can fabricate more complex mold-superstructure in an addressable and flexible way like lego bricks.
