Abstract

Dielectrophoretic force has been used to manipulate and control the biological microparticles. This technique has been used for various purposes such the cell trapping, cell sorting and separating the different biological particles suspended in a buffer solution. The strength of dielectrophoretic force depends on different features related to the cell dielectric features and geometry of the electrodes. Label-free and non-invasive techniques are considered promising in the analysis of the cell. The impedance spectroscopy is matching with the advantages of these techniques. In this paper, we study the influence of the modification of the geometry of the electrodes as the source of dielectrophoresis force on impedance spectroscopy techniques. The main target is to enhance the sensitivity of the system to differentiate between the cells with allow conductivity.
