The objective of this project is to examine the transport rate in               polymers as a means of assessing the feasibility of using synthetic             polymerized vesicles as separation vehicles to concentrate selected             species from dilute solutions.  The unique advantage enjoyed by the             polymerized vesicles is that their membranes are very thin, typically           five nanometers.  As such, the species transport rate can be greatly            enhanced.  Two specific issues will be addressed in this work:  the             effect of polymerization on membrane permeabilities; and the                    incorporation of chemical carriers with preserved functional                    activities in polymerized vesicles membranes.  The labeled tracer               technique will be used to study the membrane permeability.  Marker              leakage tests will be conducted to evaluate the stability of                    polymerized vesicles after the incorporation of chemical carriers.              The activities of chemical carriers in polymeric membranes will be              compared with those in monomeric membranes.                                                                                                                     Vesicles are of considerable research interest in the area of drug              delivery, separation technology, solar energy conversion, catalysis,            and chemical sensing.  The transport results from this project will             establish the long term framework for the study of polymerized                  vesicles as separation vehicles in an uphill active transport mode.
