title: Effect of dehydration on photoinduced transformation in gelatin films made with 14-fluoro bacteriorhodopsin derivatives.
abstract: Photoinduced transformation in gelatin films made with 14-fluoro bacteriorhodopsin derivatives, both wild-type (WT) and D96N mutant, were studied. Spectral and kinetic peculiarities for these two types of samples were compared over a wide range of relative humidity (9-92%). Analysis of the results considered two existing photoinduced processes that occur in suspensions and films of corresponding pigments. It was demonstrated that there is a range of humidity in which the performance of fluorine WT bacteriorhodopsin gelatin films may offer a technological advantage compared with fluorine D96N bacteriorhodopsin.
