title: Electroosmotic-capillary penetration in circular microchannels.
abstract: Electroosmotic forces can be used to promote penetration of electrolytes in microcapillaries. Analytical solutions for the dynamics of penetration are provided. The investigation includes both the electroosmotic and Poiseuille flows. For horizontal microcapillaries, the expression extends the Lucas-Washburn equation to account for the presence of electroosmotic effects. An analytical solution is also obtained for the case where gravity effects come into play.
