Novel dynamic, polymeric membrane structures have been successfully prepared and used in electrochemically facilitated transport and separation of proteins. A high purity of human serum albumin (HSA) can be separated from a mixture containing equimolar concentrations of HSA and Myoglobin. Quartz crystal microbalance studies show that, in these cases of transport and separation, the overriding controlling factor was electrochemical control, although polymer/protein interactions do affect the transport fluxes.
