Title: Optically induced electrokinetic patterning and manipulation of particles

Abstract: This fluid dynamics video will illustrate an optically induced electrokinetic technique for non-invasive particle manipulation on the surface of a parallel-plate gold/indium tin oxide (ITO) electrode that is illuminated with near-infrared (1064 nm) optical patterns and biased with an alternating current (AC) signal. This technique generates strong microfluidic vortices that is constructively used to dynamically and rapidly aggregate particle groups at low frequencies.
