Baylon-Cardiel, J.L.; Lapizco-Encinas,B.L.;Reyes-Betanzo,C.; Chavez-Santoscoy,A.V.; Martınez-Chapa, S.O. Prediction of trapping zones in an insulator-based dielectrophoretic device Lab-on-a-Chip, 2009, 9, 2896–2901.


A mathematical model is implemented to study the performance of an insulator-based dielectrophoretic device. The geometry of the device was captured in a computational model that solves Laplace equation within an array of cylindrical insulating structures. From the mathematical model it was possible to predict the location and magnitude of the zones of dielectrophoretic trapping of microparticles. Simulation and experimental results of trapping zones are compared for different operating conditions.
