由于沃森-克里克碱基配对的精确性和可预测性，DNA最近已经成为一种用于创建纳米级电子结构和器件的强大而新颖的材料。基于级联的DNA链置换（DSD）反应，设计了复杂的多层DNA分子电路，以实现不同的功能，特别是可靠和强大的逻辑计算。本文设计了一种用于十进制数显示的代码转换电路，它可用于计算七段数码管的逻辑状态。基于多层可逆DNA链置换反应，提出了相应的双轨跷跷板级联电路。仿真结果表明，分子逻辑电路用于十进制数显示是有效可行的。
Duing to the precision and predictability of Watson-Crick base pairing, DNA has recently emerged as a powerful and novel material for creating nano-scale electronic architectures and devices. Based on the cascaded DNA strand displacement (DSD) reactions, sophisticated multilayered DNA molecular circuits have been rationally designed to perform different functions, especially reliable and powerful logic computing. In this paper, a code converter circuit, which can be used to compute logic states of a seven-segment digital tube, is designed for decimal numbers displaying. Corresponding dualrail seesaw cascade circuit has been translated based on the multilayered reversible DNA strand displacement reactions. The simulation results show that the molecular logic circuits are effective and feasible for decimal numbers displaying.
