In the past few years, there has been a rapid growth of sample-in/answer-out micro total analysis technology (also called lab-on-chip). These platforms can integrate standardized lab protocols in a single device. Initially, continuous flow systems have been the default approach for fluid handling for these technologies, however, the use of droplet-based system have become increasingly popular. Droplet handling methods are often the source of system complexity and operational problems. For example, these methods often require incorporation of complex microfluidic components such as: micropumps, microvalve, tube connections and other active controls that require external off-chip controllers. Therefore, an in-depth understanding of droplet dynamics behavior is essential for improving the overall efficiency of droplet-based microfluidic systems. Especially those systems that employ passive on-chip droplet manipulation.
