报告摘要：
Microfluidics and nanofluidics play key roles in the development of various Lab-on-Chip technologies. The key microfluidic functions required in various lab-on-a-chip devices include pumping and mixing liquids, controlling bio-reactions, dispensing samples and reagents, and separating molecules and cells/particles. At microscale, various electrokinetic phenomena originate from the electrostatic charges or induced charges at the solid-liquid interfaces and the interactions of these charges with the applied electric field. These electrokinetic phenomena, including electroosmosis, electrophoresis and dielectrophoresis are critical to variety of microfluidic processes and technology. Using electrokinetic microfluidics can realize many fluidic functions and can make the Lab-on-a-chip devices fully automatic, independent of external support (e.g., tubing, valves and pump), and truly portable. Therefore, understanding, modeling and controlling of various electrokinetic microfluidic phenomena and processes are essential to systematic design and operation control of the lab-on-a-chip systems.
This presentation will explain the principles of these electrokinetic microfluidic and nanofluidic processes and how they are used in lab-on-a-chip devices, including electrical double layer, electroosmotic flow, electrophoresis, dielctrophoresis and induced charge electroosmotic flow. Several methods of velocity measurement in microfluidics will be reviewed. Some examples of microfluidic lab-on-a-chip devices such as real-time PCR chip, immunoassay chip and flow cytometer chip will be presented.
