【Abstract】 Objective With the increasing demand for computation, DNA computing has garnered extensive attention in computational science, particularly in the field of Boolean logic operations. Methods A DNA computing model for handling the Boolean matrix product problem was constructed by combining DNA strand displacement with switching circuits. The model mainly comprised three parts: upstream switches, downstream switches, and fluorescent reporter gates. The upstream and downstream switches input, processed, and transmitted signals, while the fluorescent reporter gates determined the output value of the Boolean operations by detecting the presence or absence of fluorescent signals. To validate the proposed model’s effectiveness, simulations were conducted by using Visual DSD software. Results The results indicated that the proposed computing model accurately performed Boolean matrix calculations, proving its effectiveness and feasibility. Conclusion The study demonstrates the strong potential and practical application prospects of DNA strand displacement technology in algebraic computation problems and advances the application and development of switching circuits in molecular computing, while providing important tools and methods for future molecular computers and bio-computing technologies.更多还原
