    Numerical analysis of a dielectrophoresis field-flow fractionation device for the separation of multiple cell types

    , Article Journal of Separation Science ; Volume 40, Issue 20 , 2017 , Pages 4067-4075 ; 16159306 (ISSN) Shamloo, A ; Kamali, A ; Sharif University of Technology
    Abstract
    In this study, a dielectrophoresis field-flow fractionation device was analyzed using a numerical simulation method and the behaviors of a set of different cells were investigated. By reducing the alternating current frequency of the electrodes from the value used in the original setup configuration and increasing the number of exit channels, total discrimination in cell trajectories and subsequent separation of four cell types were achieved. Cells were differentiated based on their size and dielectric response that are represented in their real part of Clausius–Mossotti factor at different frequencies. A number of novel designs were also proposed based on the original setup configuration....
