Facile functionalization of graphene oxide sheets on gold surface results in complexation-enhanced electrochemical detection of heavy metal ions, shown here for Pb<sup>2+</sup>, Cu<sup>2+</sup> and Hg<sup>2+</sup>, with improved detection limits by two orders of magnitude relative to the control electrode.
