Particle-sorting in Microfluidic system by AC power and Optical force
Preprocessing filtration in "Lab-on-a-chip" systems

Approach:

The proposed system can sort particles in micro-fluids flexibly by the electro-kinetics with AC power, and the optical force.   Firstly, the nonlinear electro-osmosis flow induced by AC electric field concentrates suspended micro-particles into a certain zoneon the electrode of the substrate.  Secondly, the concentrated particles are migrated into a collection fluidic layer/
