In recent years, the development of biological computers is becoming faster and faster, in order to make the logical operation algorithms of biological computers more mature and stable, a new idea for the code lock logic circuit is proposed based on DNA strand displacement by using the dual-rail method. The code lock is designed by four input signals and one conversion input signal. Only when the four input codes are correct and the conversion signal code is turned on, the password lock will be in open state, otherwise the password lock will produce an alarm signal, stopping outside invasion timely. The information of key is processed to obtain the correct password; finally, the experimental simulation results are obtained by Visual DSD software. The results analysis show that the designed code lock circuit is effective, which may provide a good technical support and a good theoretical basis in biological computers development.

Strand Displacement Reaction

Because of its outstanding advantages, DNA strand displacement (DSD) reaction has been widely used for signals processing and molecular logic circuit constructing. Two digital logic circuits are constructed in this paper. One is the encoder circuit with four inputs and two outputs, and the other is the decoder circuit with two inputs and four outputs. Of particular interest to us is the multicolor fluorescent gold nanoprobe detection part, where a gold nanoparticle is modified with multicolor fluorophores which exploits the ultrahigh quenching ability of gold nanoparticles (AuNPs). Finally, the circuits can be programmed and simulated with the software Visual DSD. The simulated results based on DSD show that the molecular circuits constructed in this paper is reliable and effective, which has wide prospects in logical circuits and nano-electronics study.

Decision Circuit

In the development of electronic technology integrated circuits, researchers focus on new calculation methods and new calculation models. The alternative technology of DNA strands is the rapid development of existed biotechnological methods for calculating new types of faster growth. In addition, a new idea for the odd judgment logic circuit based on DNA strand displacement reaction technology is proposed to solve practical problems in mathematics, and which is widely used for those various logic circuits and computing systems to acquire important roles in biological computers. The operational design of the decision circuit is also essential for the logical computing of biological computers. The odd-numbered decision circuit represents the input and output signals during the design process, and that is designed to have the number of single-chain structures of four input signals and one output signal. Finally, the molecular logic circuit is formed by using a primary seesaw circuit. From the simulation results about the dual-rail logic circuit design and the present invention, the idea of using an alternative technology is derived, and the logic circuit deserves a very reliable design. It is a good technical support and a good theoretical basis provided for the future development of biological computers through the odd judgment logic circuit.
