The self‐assembled glutathione (γ‐L‐glutamyl‐L‐cysteinyl‐glycine, GSH) monolayer was formed on a gold electrode via a 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)63– as a probe ion. These ions were found to open the ion gate with a few micromoles, and the effect was in the order of La3+ > Eu3+ Lu3+.
