Comment on Theoretical model of electrode polarisation and AC electroosmotic fluid flow in planar electrode arrays.
Journal of Colloid and Interface Science, 243, (1), . (doi:10.1006/jcis.2001.7957).
Recent experiments have shown that an AC electric field induces steady fluid flow at or near the surfaces of microelectrodes. The flow velocity is a function of frequency and applied voltage and deriving a full theoretical model has proved difficult. Recently in this journal, M. Scott, K. V. I. S. Kaler, and R. Paul (J. Colloid Interface Sci.238, 449 (2001)) presented a new theoretical model that not only is less comprehensive than previous ones but also is in direct contradiction to established fundamental principles of electrokinetics.
