Models

1. The difussion of the chemoattractant through the medium.
2. The motion of the bacterias through the medium due to the gradient on the chemoattractant concentration.
3. The circuits and devices for the chemoattractant generation within the bacteria.

For the first two points, we have developed a simulation using Java. The explanation of the simulation can be found in the Chemotaxis link below. Moreover, you can download the bacterial crowding simulation here

The circuits and transduction signals inside the cell is simulated by using Matlab's Simbiology Toolbox. The model and results can be found in the Signaling link below.
