Conductivity types (i.e., insulator, semiconductor, and conductor) can be tuned by varying the size of metallic nanoparticles. DNA origami, a molecular self-assembly technique, has promise to programmatically self-assemble nanoparticles (NPs) with nanometer precision. The work presented here demonstrates the programmatic self-assembly of AuNPs on DNA origami nanotubes (NTs). DNA origami NTs were also functionalized with positively charged Au clusters. DNA origami NTs, both bare and functionalized with Au, were electrically characterized using DC current-voltage (DC-IV) measurements. The measurements showed that bare, undecorated DNA NTs behaved as an insulator, whereas linear, ohmic conductivity was observed for Au enhanced Au decorated NTs. …
