Protein-functionalized biomimetic membranes, based upon a triblock copolymer simulating a natural lipid bilayer in a single chain, serves as a core technology for applications in bioenergetics. Monolayers of block copolymer, which simulates the hydrophilic-hydrophobic-hydrophilic chain of a natural cell membrane, can be formed by Langmuir-Blodgett (LB) deposition and provides a favorable environment for protein refolding. Large-scale membrane formation is achieved using LB deposition on a variety of substrates, such as gold, quartz, silicon, and Nafion®. We have successfully inserted membrane proteins, such as the light-activated proton pump, bacteriorhodopsin (BR) and the pH/voltage-gateable porin, Outermembrane Protein F (OmpF), into large-area LB monolayers. We have also established sustained protein functionality in films through the measurement of light-activated proton transport.
