ELECTROKINETIC TRANSPORT OF AQUEOUS ELECTROLYTES IN POLYSTYRENE MICROCHIPS
Original language description
Electrokinetically driven polystyrene microchips for transportation of aqueous electrolytes were recently developed in our lab. However, these chips suffer from some disadvantages, e.g., irreproducible dimensions of the transport channels, unknown valueof the effectively applied voltage, and difficult implementation of the source electrodes. In this work, we have developed an improved single-capillary microfluidic chip with a well-defined geometry. The applied voltage imposed on the microchannel is measured by a pair of auxiliary electrodes. A gigaohmic resistor is inserted between these electrodes in order to measure the applied voltage. The characteristics of the electrokinetic flow, i.e., zeta-potential, electroosmotic mobility and velocity of theelectrokinetic flow are evaluated by the conductivity method. The obtained results are discussed and their dependence on the applied voltage is presented. The electrokinetic characteristics are being used for the electroosmotic control of
