Abstract: Highly oriented purple-membrane films of bacteriorhodopsin were obtained using external electrical field between two ITO (Indium Tin Oxide) supports. Purple membrane films, highly oriented in one direction showed 300 mV of photo-voltage while being illuminated by cold light lamp. Concentration of bacteriorhodopsin in purple membranes (bR in PM) and salt concentration were screened in order to find optimal conditions for maximizing the photo-voltage. The dependence of electrical properties of the films from light irradiation was investigated. Results obtained in this work might be important for optogenetic tools and for creating bio solar cells based on photosensitive membrane proteins.
