Biosensor
Our biosensor model is a continuation of the previously exposed transport and accumulation model with the addition of the production of luciferase as a function of ArsR|As concentration. In this way, we can relate the concentration of extracellular As to the production of luciferase.
ODEs
The ODEs that describe the kinetics of the biosensor modules include all the assumptions presented in the core model and the equations presented for the accumulation and transport module.
