| Description |
A selective and sensitive method is reported for the
detection of dopamine (DA) by using electro-reduced
graphene oxide (er-GO) supported walnut shape nickel nanocomposite
(er-GO-Ni) modified glassy carbon electrode. The
surface morphological characterizations reveal that the Ni
nanoparticles were homogeneously distributed on the er-GO
nanosheets. Subsequently the electrochemical study shows an
excellent selectivity, reproducibility, low detection limit (10
± 0.03 nM), high sensitivity (23.3 nA·μM−1
), and reasonably
wide linear range (0.05–50 μM) for the detection of DA at
+0.1 V vs SCE. The selectivity for DA over ascorbic acid and
uric acid is attributed to the charge-based discrimination of the
modified electrode. An excellent correspondence of calculated
and reported rate constant for the DA oxidation is also obtained
by hydrodynamic experiments using a rotating disk
electrode.
