Assembly of Single‐Walled Carbon Nanotubes on DNA‐Origami Templates through Streptavidin–Biotin Interaction

Precise positioning of carbon nanotubes (CNTs) on DNA-origami structures is achieved by utilization of simple streptavidin–biotin interactions. Assembly of both single CNT and CNT cross-junctions on DNA-origami templates with relatively high yield is demonstrated. The assembly of a single nanowire on a DNA-origami nanoscale template is potentially useful for sensing applications, whereas cross-junctions can be utilized for the fabrication of electrical devices (e.g., transistors). The simplicity and cost efficiency of the proposed method make it a promising tool for controlled and accurate assembly of devices and circuits on the nanoscale.
