    In this work, the authors show that an aqueous solution of Polyethylene oxide - Polypropylene oxide - Polyethylene oxide (PEO-PPO-PEO) will self-assemble into a lamellar structures in the presence of Light Harvesting Complex II (LHCII).  In the absence of LHCII, PEO-PPO-PEO form micelles.  Moreover, they show that when a hexachloroplatinate solution is added, LHCII will produce hydrogen gas.  Specifically, after 5 light cycles sufficient Pt catalyst has been photo-precipitated to act as electron acceptors, and by the 14th light cycle, 6.4 umol hydrogen / (hour mg Chlorophyll) was observed.  H2 production continued for over 100 hours.
