This short overview discusses the fundamental elements of moving fluids in lab-on-a-chip (LOC) systems. Liquid flow in such systems is usually either single-phase channel flow or droplet flow on a surface (or between two surfaces). A primary characteristic of all flows considered here is that they are laminar flows, which provide a series of benefits as well as some challenges. Some of such basic elements described in this chapter are channel flows, pressure driven flow, electroosmotic driven flow, capillary effects, surface forces, mixing and two-phase flow read more ...
