Educational Short Review on the Electrokinetic Mixing in Microfluidic Devices
Abstract
Electrokinetics is highly useful in microfluidic lab-on-a-chip systems or micro total analysis systems for the applications in biological or chemical assays. Microfluidic systems based on electrokinetics can be used as portable devices by connecting small batteries. Micro-mixing in microfluidic lab-on-a-chip systems is highly important due to the low Reynolds number flows of liquid samples containing analytes and reagents. Micro-mixing using electrokinetics may include electrowetting-on-dielectric, dielectrophoresis and electroosmosis. In general, electrokinetics-based micro-mixing is either active mixing or passive mixing. This educational short review is authored as the study material for proposed elective-course on Microfluidics (M. Tech, Theory) in the Department of Mechanical Engineering of the National Institute of Technology, Arunachal Pradesh, India.
