Jc. Crocker et Dg. Grier, MICROSCOPIC MEASUREMENT OF THE PAIR INTERACTION POTENTIAL OF CHARGE-STABILIZED COLLOID, Physical review letters, 73(2), 1994, pp. 352-355
We present a microscopic measurement of the interaction potential betw
een isolated pairs of charged colloidal spheres. The measured spatial
dependence of the potential is consistent with the screened Coulomb re
pulsion expected from the Derjaguin-Landau-Verwey-Overbeek theory of c
olloidal interactions.
