Optically induced electrokinetic patterning and manipulation of particles

Fluid Dynamics 2015-05-13 v2

Abstract

This fluid dynamics video showcases how optically induced electrokinetic forces can be used to drive three-dimensional micro-vortices. The strong microfluidic vortices are used constructively in conjunction with other electrokinetic forces to dynamically and rapidly aggregate particle groups. Particle manipulation is achieved 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 a low frequency (<< 100 kHz) alternating current (AC) signal. The fluid dynamics video shows how electrokinetically driven flows in the microdomain can be used for non-invasive particle manipulation.
