14-fluorobacteriorhodopsin gelatin films: performance at different relative humidities
Dehydration effects on gelatin films of the 14-F wild type (WT) and 14-F D96N were studied. Spectral and kinetic characteristics were monitored over a wide range of relative humidity (9–92%). A range of humidity has been defined for each pigment, in which spectral and kinetic characteristics were changed in a desired direction. The results obtained confirmed our earlier suggestion about the existence of two photoinduced processes that occur in suspension and films of the pigments. It was shown that the 14F-WT gelatin films may offer a technological advantage relative to those based on 14-F D96N.
