Abstract
The self-assembled glutathione (gamma-L-glutamyl-L-cysteinyl-glycine, GSH) monolayer was formed on a gold electrode via sulfur attachment of the cysteinyl residue. The effect of lanthanide ions (La3+, Eu3+ and Lu3+) on the ion-gate behavior of this electrode was studied by using cyclic voltammetry (CV) and Fe(CN)(6)(3-) as a probe ion. These ions w ere found to open the ion gate with a few micromoles, and the effect w as in the order of La3+ > EU(3+) > LU(3+).
