Abstract

A new technology to pattern surface charges, either negatively or positively, using a standard photolithography process is introduced. Unlimited flow patterns can be generated under an externally applied electric field by electro-osmotic and electrophoretic driving forces to enable fine control of fluid motion in microfluidic devices. Two basic flows, shear and vortical, have been realized experimentally to demonstrate the tremendous potential of this technology, especially in analytical microsystems for genomics or cell biology.
