Claim:
Process for the analysis of interactions of substances or materials with surfaces or interfaces made from amphiphilic molecules for determining binding constants and/or partition coefficients, in which the amphiphilic molecules arranged in a fluid state bilayer are fixed to a carrier as the stationary solid by nonspecific, intermolecular forces so that the amphiphilic molecules are unimpeded in their lateral diffusion and (a) the substances or materials to be analyzed present in an aqueous, mobile phase and the carrier with the amphiphilic molecules are brought into contact, (b) the carrier with the amphiphilic molecules and the substances or materials interacting therewith are separated from the mobile phase, (c) the concentrations of the substances or materials to be analyzed are determined in the mobile phase and/or in the phase with the carrier, and (d) the interactions of the substances or materials are analyzed and binding constants or partition coefficients are determined.
