The use of self-assembly techniques may open new possibilities in scaling down electronic circuits to their ultimate limits. Deoxyribonucleic acid (DNA) nanotechnology has already demonstrated that it can provide valuable tools for the creation of nanostructures of arbitrary shape, therefore presenting an ideal platform for the development of nanoelectronic circuits. So far, however, the electronic properties of DNA nanostructures are mostly insulating, thus limiting the use of the nanostructures in electronic circuits. Therefore, methods have been investigated that use the DNA nanostructures as templates for the deposition of electrically conducting materials along the DNA strands. The most simple such structure is given by metallic nanowires formed by deposition of metals along the DNA nanostructures. Here, we review the fabrication and the characterization of the electronic properties of nanowires, which were created using these methods.
使用自组装技术可能会为将电子电路缩小到其极限开辟新的可能性。脱氧核糖核酸 (DNA) 纳米技术已经证明，它可以为任意形状的纳米结构的创建提供有价值的工具，因此为纳米电子电路的发展提供了理想的平台。然而，到目前为止，DNA 纳米结构的电子特性大多是绝缘的，从而限制了这些纳米结构在电子电路中的应用。因此，人们研究了使用 DNA 纳米结构作为模板，沿着 DNA 链沉积导电材料的方法。最简单的结构是通过沿着 DNA 纳米结构沉积金属而形成的金属纳米线。在这里，我们回顾了使用这些方法创建的纳米线的制造和电子特性的表征。
