    Abstract

    Digital video microscopy measurements of the equilibrium pair potentials for charged colloidal spheres under varying degrees of confinement were performed. The measurements revealed strong and long-ranged like-charge colloidal attractions not only between PS spheres confined to the midplane between parallel glass walls, but also between more weakly charged silica colloid sedimented into a monolayer above a glass wall.
