Abstract
In recent years, DNA strand displacement technology has played a significant role in DNA computing. In this paper, a five-bit square-root digital logic circuit based on DNA strand displacement is designed by using a simple DNA reaction mechanism. The whole reaction process of logic circuit operations can be programmed and simulated through using the Visual DSD simulation software. According to the simulation results, the square-root logic circuit is feasible to achieve the desired logical computations. Through analyzing the simulation results, the feasibility of the designed circuit is demonstrated. And it is proves that DNA strand displacement may have a great potential and bright prospect in the construction of large-scale logic circuits.
