Electrowetting and Droplet Transport in Digital Microfluidic Chips for Mixing Applications

Microfluidics- based biochips have varies applications like high throughput analyses, DNA sequencing, automated drug discovery, real time bio-molecular recognition, \ud parallel immunoassays, single cell studies and protein RNA interaction and environmental toxicity monitoring. Based upon the fluid flow pattern microfluidic based devices can be categorized in two types. They are continuous flow microfluidic device and discrete flow microfluidic device or digital microfluidic. The continuous flow uses permanently etched microchannels, micro-pumps, and micro-valves for the application such as mixing, splitting, and transportation. In contrast to this discrete type flow uses array of electrodes, voltage to controlled droplet independently for the same application
