Abstract

Abstract

DNA strand displacement technology has the characteristics of spontaneity, parallelism, programmability and dynamic cascade, which is widely used to solve mathematical problems. In this paper, a two-bit subtracter is designed by using Gray code encoding and DNA strand displacement technology to extend the operation of DNA subtraction. Finally, Visual DSD software is used to simulate the two-bit subtracter. The circuit, with the strong parallelism and expansibility, achieves the expected function. It can be used in combination with other biochemical circuits.
