Introduction DNA, carrying the genetic facts essential for the synthesis of RNA and proteins, is definitely an important biological molecule for controlling several difficult life functions. In cell, transcription activities of genes are controlled by DNA signaling circuits, where certain DNA signals are manipulated, causing them to interact with each other, as a result regulating gene networks. Not too long ago, several artificial DNA circuits have already been established and broadly applied to a lot of fields including healthcare diagnosis [1], molecular detection, and information processing [40]. Specifically, synthetic DNA circuits, developed and constructed in vitro, execute a vital part in properly controlling the gene networks in cell [113]. Synthetic DNA circuits have been demonstrated as possessing superiority in simulating and regulating DNA signaling, as a result of properties of programmability and Natural Product Library Epigenetics simple operation [148].

Recently, several different bioengineering and biocomputing functions happen to be regulated by varying the architectures and integrations of DNA circuits, which include their signal simulation [5,22], the molecular switch, catalytic cycle, cascade amplification [230], and logic gates [317]. Actually, the majority of the DNA circuits are implemented and regulated for the DNA strand displacement, whereby the longer DNA strand is in a position to hybridize with all the complementary strand to displace the shorter a single [380]. By way of a DNA strand displacement reaction (SDR), a synthetic DNA circuit could be employed to precisely regulate complicated gene networks and molecular biosystems, e.g., DNA neural network systems which might be constructed to implement pattern recognition [41]. Moreover, by taking advantage of each DNA SDR and enzyme assisted reactions, extra complex logic functions might be realized, for example the multilayer DNA circuit-based logic gate that has been established by Song, T et. al. to calculate a four-digit input square root in binary [42]. Additionally, by using a synthetic DNA circuit, the dynamic nanoparticle self-assembly process can be adequately controlled to construct specific nanostructures [436]. One example is, the spatial arrangement of gold nanoparticles is often controlled.
