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.
在此，我们提出了一种以DNA作为功能连接体介导的单壁碳纳米管（SWCNT）线性连接体的可控组装策略。我们通过特定的DNA序列设计和手性选择，利用两种不同手性的SWCNT来证明这一点。SWCNT侧壁上的链霉亲和素和金纳米颗粒标记表明，在每个单独的碳纳米管- DNA -碳纳米管连接体中存在两种不同的手性。这些一维纳米杂化物进一步从溶液组装成器件。我们开发的方法对于基于碳纳米管的功能纳米杂化物的组装以实现功能应用具有普遍适用性。
