Abstract
We present a microscopic measurement of the interaction potential between isolated pairs of charged colloidal spheres. The measured spatial dependence of the potential is consistent with the screened Coulomb repulsion expected from the Derjaguin-Landau-Verwey-Overbeek theory of colloidal interactions.
