自组装和电子特性的结合以及其真正的纳米尺度使DNA成为单分子电子学构建块的有希望的候选者。我们认为，固有的双螺旋构象的DNA链提供了一种可能性，驱动电流通过DNA的垂直电场（门控）。在一个简单的模型方法中证明了聚（G）-聚（C）合成DNA中的晶体管效应。我们提出了实验设置来观察预测的效果并讨论DNA可能的设备应用。特别是，我们提出了江崎二极管的单分子类似物的设计。
The combination of self-assembly and electronic properties as well as its true nanoscale dimensions make DNA a promising candidate for a building block of single molecule electronics. We argue that the intrinsic double helix conformation of the DNA strands provides a possibility to drive the electric current through the DNA by the perpendicular electric (gating) field. The transistor effect in the poly(G)-poly(C) synthetic DNA is demonstrated within a simple model approach. We put forward experimental setups to observe the predicted effect and discuss possible device applications of DNA. In particular, we propose a design of the single molecule analog of the Esaki diode.
