Electrokinetic manipulation of biomolecules

Electrokinetics in microfluidic system provides effective molecular manipulation technique in micro/nano domain, which matches the length scale of biomolecules. A lot of demonstrations have been reported and shown the manipulation of different biomolecules using different kinds of electrokinetic phenomena. This chapter reviewed the most commonly used electrokinetic phenomena including DC electrophoresis, AC electrophoresis, DC electroosmosis, AC electroosmosis, electrowetting, and opto-electrically induced electrokinetics. The principle behind and recent developments on the electrokinetic manipulation will be discussed. An updated and systematic in-depth discussion is provided in the field of electrokinetic manipulation.
