Imagine holding a business-card-sized, fully functional biomedical diagnostic lab in your hand. Lab-on-a-chip devices are miniaturized bio-medical laboratories on a small glass/plastic chip. These lab chips can duplicate the specialized functions of their room-sized counterparts such as clinical diagnoses and tests. 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. Using electrokinetic microfluidics to realize these functions can make the devices fully automatic, independent of external support, and truly portable. 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 processes and how they are used in lab-on-a-chip devices. Some lab-on-a-chip devices such as real-time PCR Lab-on-a-Chip, immunoassay Lab-on-a-Chip and flow cytometer Lab-on-a-Chip developed in Dr. Li’s lab will be introduced.
Dongqing Li obtained his Ph.D. degree at the University of Toronto in 1991. In 1993, Dr. Li joined the faculty of the Department of Mechanical Engineering, University of Alberta, where he was promoted to the rank of full professor in 1999. He later joined the Department of Mechanical and Industrial Engineering, University of Toronto, in 2000 as a tenured full professor. From September 2005, Dr. Li was the H. Fort Flowers Chair Professor of Mechanical Engineering at Vanderbilt University. Since September 2008, Dr. Li joined the University of Waterloo as the Canada Research Chair (Tier 1) in Microfluidics and Nanofluidics. Dr. Li’s research is in the area of microfluidics, nanofluidics and lab-on-a-chip technology. Dr. Li has published over 240 papers in leading international journals, many book chapters and several books including "Electrokinetics in Microfluidics", "Encyclopaedia of Microfluidics and Nanofluidics". He is the Editor-in-Chief of an international journal—Microfluidics and Nanofluidics.
