Biosensor architecture: A cell‐based biosensor works by the input entering the cell being detected by the sensor component (sensor) of the genetic circuit which is a gene constitutively expressing a transcription factor (TF) which then activates the generation of a reporter protein (output) by binding and activating the promoter responsive to the transcription factor (PTF).
