Abstract
An experimental and theoretical investigation of two colloidal spheres diffusion near a flat plate was carried out. It was observed that a confining surface can influence colloidal dynamics even at large separations. Further, results reveal that wall-induced hydrodynamic interactions may have influenced nonequilibrium optical tweezer measurements of confined colloidal interactions, and could have contributed to the attractions between like-charged spheres.
