Abstract
Photodetectors can be made that contain bacteriorhodopsin (BR) as the photoactive material. These photodetectors consist of dried oriented purple membrane sheets of BR sandwiched between transparent electrodes. The oriented BR layer is made by electrodeposition from a solution of purple membrane in distilled water. The photoresponse is due to a very rapid light-induced polarization of the sample. Experiments indicate that the rapid polarization induces a photovoltage with a rise time in the picosecond time domain. An experiment can be devised to allow the ultrafast photoresponse of these BR based photodetectors to be measured.
