Multilayer films have been prepared by the sequential electrostatic adsorption of poly(L-lysine) and hyaluronic acid onto charged silicon surfaces from dilute aqueous solutions under various pH conditions. Microelectrophoresis was used to examine the local acid-base equilibria of the polyelectrolytes within the films as a function of the total number of layers in the film and the assembly solution pH. The acid-base dissociation constants were observed to deviate significantly from dilute… CONTINUE READING
