DNA-Guided Assemblies toward Nanoelectronic Applications

Abstract

Programmable DNA-guided self-assembly of nanoscale functional materials is of great interest in the context of nanofabrication or nanoelectronics. Attributed to its unique sequence programmability and precisely defined dimension, DNA has been used as a template for constructing ordered one-, two-, and three-dimensional architectures with organic, inorganic, and polymeric building blocks via various self-assembly strategies. Moreover, the accessible integration capability of DNA with diverse electronics-related materials propels the field of DNA-guided assemblies toward nanoelectronic applications. In this review, we outline the development in the area of DNA-guided assemblies that are constructed from carbon nanotubes, fullerenes, polymers, metals, metal oxides, and minerals using various strategies, with the focus on the bottom-up DNA-guided conducting, semiconducting, and insulating nanomaterials applied on nanoelectronics. We also review some bottom-up and top-down hybrid methods that precisely immobilize functional DNA-guided materials on substrates with high throughput. Finally, we describe the challenges in nanofabrication and potential applications of DNA-guided assemblies in nanoelectronics.

Application of a quantum genetic algorithm and QTAIM analysis in the study of structural and electronic properties of neutral bimetallic clusters NaxLiy (4 ≤ x + y ≤ 10)

“…A nano-sized cluster of atoms or molecules has a particular set of properties that depends on its composition and size-a distinguishing feature when compared to the condensed matter [1,2]. The understanding of these properties has allowed the design of a wide range of nanomaterials, which are applied in medicine [1,[3][4][5][6][7][8][9][10][11][12][13][14], catalysis [11,13], semiconductors materials [15][16][17][18][19], fuel cells [16,20], etc. A prominent class of nanomaterials is the nanoalloy which may exhibit distinct properties from the pure metal clusters and it has application in the electronics and engineering fields [2,21].…”

Programmed Assembly of DNA Templates by Silver Nanowires

“…In the recent years, increasing attention has been devoted to DNA templated assemblies due to their unparalleled selfassembly and programmability properties for the precession guided nanomaterial fabrication. [1][2][3][4][5][6][7][8] For instance, the bottomup DNA-guided assemblies were utilized to integrate several functional electronic materials such as carbon nanotubes, [9][10][11] fullerenes, [12][13] polymers, [14][15][16] metals, [17][18][19] nanoclusters [20][21][22] with various DNA interaction strategies. Moreover, the programmed assembly of DNA was used to construct arbitrary shapes and patterns which intern utilized as higher order template for hierarchical organization of metallized nanowires, nanoarrays and biomaterials.…”
