Using Molecular Beacons as Paste Series Computing Model of a Logic Gate

In recent years, it has become a research focus of DNA computer to realize the Boolean logic gates by using DNA sticker model and paste system, with the research of DNA computing and DNA computer going on. But making the molecular beacon as part of the paste series has not been seen, and this paper rea- lizes the DNA computing model of logic gates with such a new method. This model has all the advantages that the previous general sticker model has. Also it is easier to operate and observe, and has higher reliability of results. With high specificity and sensitivity of molecular beacon itself, the logic gate has a more intuitive operation and observation.
