Zeta potential of particle bilayers on mica: A streaming potential study

► Formation of a particle bilayer can be studied using the streaming potential method. ► The zeta potential of bilayers approach 0.71 of the bulk value of particles forming the external layer. ► Experimental data can be used for interpretation of polyelectrolyte films in LbL processes. ► Our results can be used as reference systems for interpretation of the antigen/antibody interactions.
