DNA-Guided Assemblies toward Nanoelectronic Applications.

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.
