AC electrokinetic particle manipulation in microsystems
AC electrokinetic particle manipulation in microsystems
Lab-on-Chip systems integrate multiple functionalities on a single platform. Automated or remote manipulation and analysis of particles and fluids is a key element in microfluidic devices. Microelectrodes can be integrated into these devices to generate large electric fields and field gradients using low voltages. Electrokinetics is an attractive method for integrating particle manipulation and separation within such systems. The electrokinetic forces are easy to control by designing optimum electrode structures and choice of field and frequency. In this chapter, the theory of AC electrokinetics is reviewed and example applications for manipulation of particles are provided. The use of dielectrophoresis (DEP) for manipulating micro particles is then described, together with a discussion on scaling issues.

Abstract
Lab-on-Chip systems integrate multiple functionalities on a single platform. Automated or remote manipulation and analysis of particles and fluids is a key element in microfluidic devices. Microelectrodes can be integrated into these devices to generate large electric fields and field gradients using low voltages. Electrokinetics is an attractive method for integrating particle manipulation and separation within such systems. The electrokinetic forces are easy to control by designing optimum electrode structures and choice of field and frequency. In this chapter, the theory of AC electrokinetics is reviewed and example applications for manipulation of particles are provided. The use of dielectrophoresis (DEP) for manipulating micro particles is then described, together with a discussion on scaling issues.
