Abstract :
The deformation mechanics of a single E. coli bacterium in close proximity of a rigid quartz substrate is investigated using a two dimensional finite element model. The classical Derjaguin-Landau-Verwey-Overbeek potential is used to model the intersurface forces experienced by the bacterium. A coupling between deformation and adhesive properties is seen.
