Breaking cover : Hydroxyl radicals OH . destroy the self‐assembled monolayer (SAM) of hexanethiol on gold and mercury electrodes and thus allow the electrochemical response of the redox couple Ru 2+/3+ to be measured. On a completely SAM‐covered electrode the Ru 2+/3+ signal is absent, thus the recovery of the signal following radical attack is a reliable measure of the radical activity.
