The Research of Encoder Logic Operation Model Based on DNA Strand Displacement Reaction

As a new technology and its outstanding advantages in DNA self-assembly computing,DNA strand displacement reaction has been widely used on molecular computing field in recent years.Based on the principle of DNA self-assembly computing,logic circuit models of different logic gates were constructed.And then,the encoder logic operation models were designed according to DNA strand displacement reaction theory.when the DNA signal strands are input with others DNA strands corresponding to different logic gate molecular circuits,the new DNA signals strands can be output after a series of reactions among DNA strands.The simulation results achieved in Visual DSD software show that it is feasible and accurate for the encoder logic design operation model constructed in this paper,which is helpful for the application of molecular logic circuit research.
