The goal of the research is to develop thin gel composite membranes             for application in gel chromatography for bioseparations.  The                  proposed composite membranes will be formed by interfacially                    polymerizing onto thin porous supports.  Use of such thin gel                   composite membranes could result in large-scale bioseparations.  The            productivity, selectivity, and effective thickness of the resulting             membranes will be related to the polymerization conditions.  Water-             soluble polymers that are representative of biomolecular size will be           tagged with dye molecules and used as the permeating solutes.                   Membrane flux and selectivity will be determined with a flow-through            diffusion cell which uses a fiber optic probe colorimeter to                    instantaneously measure the downstream concentration.  This project             will stimulate further research in the area of gel-based membrane               separations.  Processes based on the thin-gel composite membrane                potentially may replace additional steps in the purification of                 proteins and other biological molecules.
