Abstract
A strong influence of bromide ion was found on voltammetry of layered films of photosynthetic reaction center (RC) protein and polyions on gold electr odes. Similar, but not identical, cyclic voltammetry peaks were observed fo r polyion films on gold with and without RC when the buffer solutions conta ined bromide ion. CVs of RC films were quite different in the absence of br omide. These new findings suggest that previously published results were bi ased by significant background peaks involving bromide ion adsorption/desor ption. (C) 2001 Elsevier Science B.V.
