Redox-initiated actuation of biology and two-hop communication. (a) Initial test with a synbio redox “transceiver” engineered to receive redox-inputs through the soxRS regulon and re-wired to respond by upregulating expression of a gene coding for a fluorescent protein. (b) Voltage-dependent response of this synbio transceiver. (c) Schematic of two-hop molecular communication involving transceiver (or relay) cells that receive a redox input and transmit a quorum sensing (QS) signaling molecule, and a “receiver” cell that receives the QS molecular input and generates a fluorescence output response. (d) Output fluorescence vs input electrical charge for this two-hop communication. Reproduced with permission from [180].
