Multiple entities interaction model through DNA based Petri Net

High-level control is an important part in developing an autonomous molecular robot made from DNA. In this paper, we report the design of DNA-based coordination model driven by multiple entities interaction to coordinate the behavior of numerous DNA agents. First, the implementation of DNA operator will be introduced. We utilize DNA Strand Displacement as the main and the only computational mechanism. Second, the equality of this operator with Petri Net model will be discussed. We show how Petri Net can be carried by DNA computation. Third, for our ultimate goal, we introduce the strategy of designing interaction model through this DNA-based Petri Net, by employing simple assembling task scenario. The correctness of the design is inferred by the result from software-based simulation.
