Time-Elapse Communication: Bacterial Communication on a Microfluidic Chip

Abstract: Bacterial populations housed in microfluidic environments can serve as transceivers for molecular communication, but the data-rates are extremely low (e.g., 10 −5 bits per second.). In this work, genetically engineered Escherichia coli bacteria were maintained in a microfluidic device where their response to a chemical stimulus was examined over time. The bacteria serve as a communication receiver where a simple modulation such as on-off keying (OOK) is achievable, although it suffers from very poor data-rates… Show more

“…An "AHL pulse" is the duration and concentration over which this AHL was delivered to the bacteria chamber. Pulse durations of 50 min which we have previously optimized 29 were used. Fluorescent images were captured once in every 10 min and post-processed using MATLAB.…”

“…This method, the so-called pulsed width modulation (PWM), has been implemented in microfluidic devices 27,28 and is often employed to synthesize biopolymers, to study the influence of their composition on their function, and to test the effect of certain molecules on the cell behavior. [29][30][31][32][33][34] Recent advancements of this technology enable independent injection of up to six different reagents and changing their concentrations in situ by up to five orders of magnitudes. 35 This level of compositional control over such a wide concentration range is difficult to achieve with co-flowing fluids.…”
