Dielectrophoretic characterization of colloidal particles using angled microelectrode arrays
Dielectrophoretic characterization of colloidal particles using angled microelectrode arrays
This paper will present a characterization of a microfluidic device with embedded
angled microelectrode arrays for the continuous flow-through dielectrophoretic separation of particles. The operation of the device is demonstrated using samples of colloidal latex spheres, achieving 100% particle deflection with low operating voltage of 10V. This characterization is essential for dielectrophoretic separation to get the specific indication for each particle type behaviour, deflection and hence separation at the end of the arrays. This paper will discuss results obtained and also detail of the theoretical background of the separation method and the optimization of separation that is achievable by choice of frequency and voltage.

Abstract
This paper will present a characterization of a microfluidic device with embedded
angled microelectrode arrays for the continuous flow-through dielectrophoretic separation of particles. The operation of the device is demonstrated using samples of colloidal latex spheres, achieving 100% particle deflection with low operating voltage of 10V. This characterization is essential for dielectrophoretic separation to get the specific indication for each particle type behaviour, deflection and hence separation at the end of the arrays. This paper will discuss results obtained and also detail of the theoretical background of the separation method and the optimization of separation that is achievable by choice of frequency and voltage.
