英文摘要A nanohybrid electrode was prepared by functionalizing reduced graphene oxide nanosheets (GNs) with gold nanoparticles (AuNP), CoS2, and an ionic liquid. It is shown to enable voltammetric determination of dopamine (DA). The AuNPs were electrodeposited onto the electrode that was first modified with CoS2 and the IL-GNs to obtain a well-defined 3-dimensional and porous structure. The nanohybrid material displays high catalytic activity and an ultrasensitive cyclic voltammetric response to DA. The peak current (best measured at a working voltage of 0.17 V vs. Ag/AgCl) increases linearly in the 0.1 to 400 mu M DA concentration range, with a 40 nM detection limit (at S/N = 3). The electrode was successfully applied to the determination of DA in spiked serum samples.
