Opto-electrical processes in a conducting polymer-bacteriorhodopsin system.
In this report, we highlight the opto-electrical processes at a conducting polymer-bacteriorhodopsin (bR) interface in presence of a voltage bias. Oriented bR on a conducting polymer substrate forms a unique hybrid system where the oxidation state of the polymer controls the optically activated proton gradient in the bR side. The internal conversion of the intermediate deprotonated M-state and the proton transfer/transport of bR at the interface can be controlled by the electrostatic environment and leads to interesting device features in this process.
