Langmuir-Blodgett films prepared from purple membranes dissolved in pu
re hexane were characterized for M-state decay kinetics and photocurre
nt production. These studies indicated that the films are preferential
ly oriented with thr cytoplasmic side of the bacteriorhodopsin molecul
e facing away from the surface of the tin oxide coated glass electrode
s. Characterization of Langmuir-Blodgett Films in high salt strongly i
ndicates that the transient photocurrents observed are directly due to
proton release and uptake and not to charge separation. Published by
