Abstract

The present paper presents an investigation to study of AC electrokinetic phenomena in microfluidics.

The results show that the variation of the width of electrodes and the gap between electrodes has no effect on the results, but if we change the height of the microcantilver, the concentration of the bonded molecules exchanged with a proportional manner and the width of reaction surface has an effect inversely proportional to the results. The results show also that increasing the length of reaction surface has a negative effect on the attachment of molecules on the surface reaction and changing the width of electrodes or the gap between electrodes changes the concentration of the bonded molecules.

The present numerical results can be considered as a contribution to the design of the microchannel used in lab-on-a-chip applications.
