In authors' opinion, GNR is an under exploited carbon nanomaterial full of properties which needs to be demonstrated. The most relevant and expected promises derived from the use of these
carbon nanomaterials in electrochemical sensing should be: (i) The electrocatalytic effect induced by graphene materials might have an effect on the redox capacity of analytes and, consequently, on the decrease of the detection potentials, which would improve the overall selectivity of the analysis. (ii) Enhancement of faradaic currents, since the large surface area of graphene detectors would permit rapid redox conversion. This implies the increase in sensitivity in the analytical procedure. (iii) Increase the resistance to passivation originated from the greater surface area of the graphene-based detectors. It implies better reproducibility in analysis, because of the lower electrode fouling.
