The silica binding module of our project is based on the expression of a chimeric transmembranal protein, OmpA-L2. This chimeric protein is composed by a OmpA domain (the transmembranal domain) and a L2 domain (the silica binding domain).
For the mathematical representation of the binding to silica particles, we proceed at the population level and take into account a saturation function. We also assume that bacteria are in the stationary phase.
The size of the particles is assumed to be greater than that of the cells.
