Chemically induced enhancement of the opto-electronic response of Halobacterium purple membrane monolayer.
Acetylation of purple membranes (PM) significantly enhances the surface photovoltage that they exhibit, if adsorbed as a monolayer on a solid surface; we suggest that this increase is due to the improved orientation of the PM on the surface.
