Well‐oriented monolayers of bacteriorhodopsin(bR)‐containing purple‐membrane patches are prepared on solid substrates (see Figure). Green‐light illumination completely converts wild‐type bR to the blue‐light‐absorbing M state, even at high humidity and pH 7. The possibility of bR‐based optoelectronic devices is significantly enhanced by systems comprised of the long‐lived M state, thus underlying the importance of this work.
