Nano Transceiver Design for Molecular Communication Based on DNA Technology

Molecular communication (MC) is a promising way to achieve the Internet of nano things (IoNTs), and the theoretical system has been gradually improved in recent years. However, previous studies have more concentrated on system modeling, often simplifying the transceiver into an ideal point model due to the absence of a detailed transceiver design. In this paper, we choose DNA, the natural material to design the MC transceiver benefited from the promoting DNA technology. Specifically, we use DNA origami technology to design the transceiver and DNA strands as the information molecules (IMs). DNA strand displacement (DSD) reactions make up to the mechanism of the transmission and reception of IMs. Furthermore, amplifier is designed based on strand displacement amplification (SDA) mechanism, and the whole MC system works under the control of a timer mechanism which is achieved by the synergy of <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\lambda$</tex> exonuclease ( <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\lambda$</tex> Exo) and fuel strands, one special DNA strands. For our designed nano transceiver, we modeled the MC system mathematically and analyzed the noise based on the properties of the transceiver. Based on the simulation results, we find the nano transceiver works well in nano-scale which promises the potential for further application in the future.
