Three-Input and Nine-Output Cubic Logical Circuit Based on DNA Strand Displacement

Abstract

The method of DNA strand displacement breaks the static thinking of DNA nanotechnology, which makes the biochemical cascade reaction, nanoscale motion and energy conversion widely used in the logic gate operating model. The cubic logical circuit of three-input and nine-output based on DNA strand displacement is designed in this article. The cubic logic circuit can be translated into the dual-rail logic circuit and the dual-rail logic circuit can be translated into the DNA seesaw logic circuit, then it can be simulated through the Visual DSD software. It demonstrated that the correctness of logic circuit through the simulation results. DNA strand displacement has gigantic capable of implementation of logical calculation which plays a momentous role in the acquirement of bio-computer, and it is most widely used in the majority computing systems. At the same time, the difficult problems in the construction of large-scale complex logic circuits can be solved, and have great significance to research.
