Abstract

Herein, we present a strategy for the controlled assembly of single-walled carbon nanotube (SWCNT) linear junctions mediated by DNA as a functional linker. We demonstrate this by employing SWCNTs of two different chiralities via the specific design of DNA sequences and chiral selection. Streptavidin and AuNP labeling of the SWCNT sidewalls demonstrate the presence of two different chirality within each individual CNT–DNA–CNT junction. These one-dimensional nanohybrids were further organized from solution to devices. The approach we developed is of general applicability for the assembly of functional nanohybrids based on carbon nanotubes toward functional applications.

DNA 介导的碳纳米管异质结组装

在此，我们提出了一种以 DNA 为功能连接体，控制单壁碳纳米管 (SWCNT) 线性连接组装的策略。我们通过 DNA 序列的特定设计和手性选择，采用了两种不同手性的 SWCNT，证明了这一点。SWCNT 侧壁的链霉亲和素和 AuNP 标记表明，每个 CNT-DNA-CNT 连接中都存在两种不同的手性。这些一维纳米混合物被进一步从溶液组织成器件。我们开发的方法普遍适用于基于碳纳米管的功能性纳米杂化组装，以实现功能性应用。
