Bacteriorhodopsin is an optoelectric protein found in the membrane of the extremophile bacterium Halobacterium salinarum. The protein creates a charge gradient across its 6 nm thickness and, when integrated with inorganic electron generation and transport materials such as titania nanotubes, may find use in a new class of photon harvesters. Bacteriorhodopsin strongly absorbs light near the 570 nm wavelength but its photoelectric activity is now shown to increase by at least 35 when integrated with ultraviolet UV-scavenging quantum dots.
