In this paper, a new modeling approach for Dielectrophoresis (DEP) based particle manipulation is presented. The proposed method fulfills missing links in finite element modeling between the multiphysic simulation and the biological behavior. This technique is amongst the first steps to develop a more complex platform covering several types of manipulations such as magnetophoresis and optics. The modeling approach is based on a hybrid interface using both ANSYS and MATLAB to link the propagation of the electrical field in the micro-channel to the particle motion. ANSYS is used to simulate the electrical propagation while MATLAB interprets the results to calculate cell displacement and send the new information to ANSYS for another turn. The beta version of the proposed technique takes into account particle shape, weight and its electrical properties. First obtained results are coherent with experimental results.

This article presents a new multiphysics modelling approach for cell manipulation by dielectrophoresis. This approach is proposed to model and predict the behavior of particles injected into a microchannel due to the application of an electrical field. The objective of this model is to better characterize microelectronic circuits dedicated to design and implement hybrid systems such as lab-on-chips integrating microelectronics and microfluidic structures. The proposed model allows to determine the required configuration of microelectronic circuits and needed control signals to generate. This model applies primarily to applications using dielectrophoresis cell separation in a microchannel. Then, by using the proposed model, the cell behaviour can be predicted using an advanced multiphysics simulation methode.
