Electrokinetic flows in microfluidic devices

The paper represents some experimental results on electroosmotic flows in microfluidic chips. We have found out that chemical and thermal processes taking place in microchip encapsulation affect the channel surface properties thus determining the electroosmotic flow mobility. It has been shown that the character of variations in the electroosmic flow rate depends on the plate surface treatment technique and materials the channeled and protective plates are made from.
