title: Influence of bromide on electrochemistry of photosynthetic reaction center films on gold electrodes.
abstract: A strong influence of bromide ion was found on voltammetry of layered films of photosynthetic reaction center (RC) protein and polyions on gold electrodes. Similar, but not identical, cyclic voltammetry peaks were observed for polyion films on gold with and without RC when the buffer solutions contained bromide ion. CVs of RC films were quite different in the absence of bromide. These new findings suggest that previously published results were biased by significant background peaks involving bromide ion adsorption/desorption.
