摘要
与非门(NAND)的本质是与门(AND)和非门(NOT)的叠加,先进行与运算,再进行非运算,它是建立DNA计算机的基础。为了实现与非门的计算,该文在DNA折纸基底上建立了一个与非门计算模型,逻辑值的输入是通过在DNA折纸基底上发生有向的杂交链式反应(HCR)来完成的,输入链先经过与门区域再经过非门区域,最后通过DNA折纸基底上是否还保留纳米金颗粒来显示计算结果的真假。利用Visual DSD对该计算模型进行仿真模拟,显示该计算模型具有较好的可行性。
The essence of NAND gate is the superposition of AND gate and NOT gate.The AND gate operation is performed first,and then the NOT gate is performed.It is the basis of the DNA computer.In order to realize the computing of NAND gate,a NAND gate computational model is established based on the DNA origami template.The inputs of the logic value are completed by the Hybridization Chain Reaction(HCR)on the DNA origami template.The input strands first react with the AND gate region and then react with the NOT gate region.The result of the reaction is shown by dynamically separation of the gold nanoparticles on the DNA origami template.The simulation of the model through Visual DSD shows that the system has the advantages of high feasibility.
