Book Description

Over the past several decades, researchers around the world have exploited a light-responsive protein called bacteriorhodopsin (bR) to create thin organic films that can function as photocells and photo-electric biotransducers. From an engineering perspective, the proton transfer mechanisms of bR purple membranes have been used to develop various optoelectronic devices. This Spotlight describes the functional molecular behavior of bacteriorhodopsin, techniques for molecular self-assembly, and applications for bioelectronic sensing and microactuation.
