Abstract/OtherAbstract:

We investigate the electrochemical properties of CVD grown graphene towards the detection of various biologically prevalent analytes including l-ascorbic acid (AA), dopamine hydrochloride (DA), β-nicotinamide adenine dinucleotide (NADH), uric acid (UA) and epinephrine (EP). We find that the observed electrochemical response of the CVD-graphene towards these select analytes does not originate from the graphene, however, from various other contributions including the presence of 'graphitic islands' on the surface of the CVD-graphene which dominate its electrochemistry. In the systems studied within, it appears at best, CVD-graphene acts akin to that of an edge plane pyrolytic graphite (EPPG) electrode constructed from highly ordered pyrolytic graphite. However, in other cases, the response of the CVD-graphene is worse than that of an EPPG electrode, which is likely due to the low O/C ratio. |
