Graphene oxide-based electrochemical sensor: a platform for ultrasensitive detection of heavy metal ions

Author affiliations

Abstract

Facile functionalization of graphene oxide sheets on gold surface results in complexation-enhanced electrochemical detection of heavy metal ions, shown here for Pb2+, Cu2+ and Hg2+, with improved detection limits by two orders of magnitude relative to the control electrode.
