DNA Origami: DNA Origami Directed Large‐Scale Fabrication of Nanostructures Resembling Room Temperature Single‐Electron Transistors (Small 21/2013)

Large-scale fabrication of room-temperature single-electron transistors core nanostructures in an unprecedented yield is achieved by using DNA self-assembly strategy, in which three gold nanorods (13 nm × 38 nm) are precisely positioned on the DNA origami surface as source, drain, and gate electrodes, with the distance between the source and drain electrodes smaller than 10 nm. As reported on page 3567 by Q. Wang and co-workers, a gold nanoparticle (4.5 nm) can be located in the center of the source and drain electrodes as Coulomb island. This delicate nanostructure cannot be achieved using state-of-art nanofabrication techniques.
