Abstract
ac-electro-osmosis is used to concentrate particles on circular gold electrodes. Localization of the concentration of particles is predicted and experimentally observed by slight modifications of the electrical parameters (frequency, voltage intensity). Efficiency evaluations of the concentrators are proposed and applied to our system and compared with the predictions. Experimental concentration on dedicated test devices is 200 times faster than classical diffusion. An optimization of the collection rate is obtained by switching the frequency signal between two determined values. This optimization allows doubling the arrival rate of particles.
