Uniformity of dry bacteriorhodopsin films

Abstract

Bacteriorhodopsin (BR) is a light-sensitive protein, which is a promising material for various technical applications, such as photosensors. The quality of dry thick BR photosensors depends on few performance characteristics. Uniformity of parameters, which have the impact on such characteristics, should be maintained during the preparation or otherwise compensated afterwards. In this thesis, uniformity examination techniques were studied. Experimental setups, which operate, based on studied techniques, were designed. Experiments, which were conducted on constructed setups, revealed a list of dependencies between BR properties and allowed to evaluate properties of sensors.
