Effects of Nanostructured Surfaces on Electro-osmotic Flow

Electro-osmotic flow (EOF) is the flow of fluid in a microchannel which is induced by an external elec-tric field. EOF originates from electrical double layer (EDL) formed spontaneously at the channel-fluid interface. The electrostatic potential at the channel wall is called the zeta potential. Nano...
