This paper summarizes the numerical contribution to a project for the detection of bioparticles present in a small volume of a liquid sample.

Dielectrophoresis (DEP) is used to enhance their transport toward the surface of a detector.

The mathematical model is composed of the electrokinetics equation for the DEP force-field calculation, and the advection-diffusion equation for the particle distribution inside the liquid sample.
