Bottom-up fabrication using DNA is a promising approach for the creation of nanoarchitectures. Accordingly, nanomaterials with specific electronic, photonic, or other functions are precisely and programmably positioned on DNA nanostructures from a disordered collection of smaller parts. These self-assembled structures offer significant potential in many domains such as sensing, drug delivery, and electronic device manufacturing. This review describes recent progress in organizing nanoscale morphologies of metals, semiconductors, and carbon nanotubes using DNA templates. We describe common substrates, DNA templates, seeding, plating, nanomaterial placement, and methods for structural and electrical characterization. Finally, our outlook for DNA-enabled bottom-up nanofabrication of materials is presented.
利用DNA进行自下而上的制造是创建纳米结构的一种很有前景的方法。因此，具有特定电子、光子或其他功能的纳米材料可以从较小部件的无序集合中精确且可编程地定位在DNA纳米结构上。这些自组装结构在传感、药物递送和电子设备制造等许多领域具有巨大潜力。本综述描述了利用DNA模板构建金属、半导体和碳纳米管纳米级形态的最新进展。我们描述了常见的底物、DNA模板、晶种、电镀、纳米材料放置以及结构和电学表征方法。最后，我们展望了基于DNA的材料自下而上的纳米制造。
