Abstract
We demonstrate that the attractive interaction measured between like-charge d colloidal spheres near a wall can be accounted for by a nonequilibrium hy drodynamic effect. We present both analytical results and Brownian dynamics simulations which quantitatively capture the one-wall experiments of Larse n and Grier [Nature (London) 385, 230 (1997)], using a single unmeasured pa rameter.
