Au nanostructures electrodeposited on graphene oxide-modified ITO glass as SERS substrates for dopamine detection in human serum

Abstract

Surface enhanced Raman scattering (SERS) is one of the best analytical tools which can identify probing molecules with an ultralow concentration. As a sensitive SERS substrate, we electrodeposited Au nanostructures on the ITO glass modified with graphene oxide, in order to detect the dopamine (10⁻⁸–10⁻⁹ M) in human serum.
