* We performed double transformations with different combinations of regulator + sensor plasmids for cross-talk experiments. We have results for our first quorum sensing experiment : fluorescence under control of wildtype lux sensor (s24) over time for different concentrations of AHL. s1 is a negative control.

* In the next weeks we will fit quorum sensing parameters thanks to the first quorum sensing experiments and our simple GFP production model, refine this Comsol diffusion model with the right quorum sensing parameters and then fit this diffusion model to diffusion experiments to find the diffusion constant.

*We have a simple GFP production model for simulation of these quorum sensing experiments, by using quasi steady state aproximations (considering that binding is much faster than transcription and diffusion) :

By using producer cells on one side of the channel and receiver cells in the other side, and putting cells in a punched cylinder in agar, we should see fluorescence appear at different times depending on the channel length (1 to 4mm) :
