A bacteriorhodopsin (bR)-based photodetector is prepared with the structure of stainless steel slide/bR film/aqueous electrolyte gel/copper electrode. The photoelectric response signal to a 10 ns laser pulse is measured. A theory on the bR photoelectric kinetics is developed based on the concept of charge displacement current and the bR photocycle rate equations. Comparison between the theoretical and experimental results proves the multiexponential process of the bR photoelectric response to a short laser pulse. The decay time constants and amplitudes of each exponential component are obtained by data fitting. (C) 2001 American Institute of Physics.
