Abstract
The results derived by Yariv and Dorfman [Phys. Fluids 19, 037101 (2007).] for the electrophoretic transport of a point-size Brownian particle in a narrow channel of periodically varying cross section are generalized to joint electrophoretic and electro-osmotic flow (or purely electro-osmotic flow, in the case of a neutral particle) in a channel possessing a uniform zeta potential by a suitable change in the definition of the Péclet number.
