SHG studies of the adsorption of the HIV-1 peptide to neutral and charged membrane mimetic phospholipid liposomes will be presented.  The adsorption free energy, the electrostatic potential which is not based on the Gouy-Chapman model, and the number of peptides adsorbed have been determined. A comparison of the electrostatic potential obtained from SHG measurements with the zeta potential obtained from electrophoresis measurements is given. SHG results of acid � base equilibria at a colloidal polymer microparticle/aqueous interface are discussed.
