DNA Origami Directed Large‐Scale Fabrication of Nanostructures Resembling Room Temperature Single‐Electron Transistors

Abstract

Room temperature single-electron transistor core nanostructures are fabricated on a large scale with DNA origami as a template with an unprecedented yield. The accuracy of DNA origami enables precise positioning of a Coulomb island in the center of a 10 nm gap between the source and the drain electrodes, which can not be realized by using state-of-the-art nanofabrication techniques.

“…[12] The synthesis of the DDPOG and G 2 Cl-18 is based on the solid-phase method developed by our group. [12] The synthesis of the DDPOG and G 2 Cl-18 is based on the solid-phase method developed by our group.…”

“…The AuNPs/AuNRs and the DNA-modified AuNPs/AuNRs were synthesized following the procedure in previous reports. [12] The synthesis of the DDPOG and G 2 Cl-18 is based on the solid-phase method developed by our group. [7,8] The detailed description can be found in the Supporting Information.…”

Programmable Assembly of Nano‐architectures through Designing Anisotropic DNA Origami Patches

“…Structural DNA nanotechnology exhibits the competence in tailoring the arrangement of NPs with accurate manufacture, synthesizing homogeneous and heterogeneous nanoclusters, and building low dimensional arrays and 3D superlattices by using DNA strands or nanostructures as the linkers or templates. Recently, DNA origami frames (DOFs) played a crucial role in mounting NPs at desired positions, while the outside DNA struts determined the NPs orientations as backbones when assembling into larger structures.…”

[37][38][39][40][41][42] However,m oderately complex nanoclusters and nanoarrays with scale between individual building blocks and largescale superlattices have not yet fully investigated, owing to the difficulty in controlling the anisotropies of the NPs and the programmable assembly process.…”

DNA-programmed self-assembly of photonic nanoarchitectures

“…These 2D architectures made of 1D building blocks with defined geometry and boundary are of fundamental significance for developing the electronic and/or optoelectronic devices. Wang and coworkers 48 reported a typical example of a T-shaped 2D nanoarchitecture comprising three AuNRs and one AuNP assembled on a rectangular DNA origami, in which the AuNRs and the AuNP act as the source, the drain and the gate electrodes and the Coulomb island, respectively. This T-shaped AuNR nanoarchitecture holds great promise for functioning as the core device in room temperature single-electron transistor (Figure 2b).…”
