Notes:
Voltammetry of adenosine after electrochemical treatment is explored. The activations scheme includes an anodic potential (+2.2 V) for 125 ms and a cathodic potential (-1.0 V) for 75 ms. Subsequent staircase voltammetry can be used to obtain both qualitative and quantitative information. This activation procedure has been applied to 11 μm carbon-fiber microelectrodes to obtain reproducible voltammograms for adenosine. To characterize this activation procedure, the effect of the magnitude and duration of both the anodic and the cathodic potentials have been studied. Data obtained suggest that the magnitude of the applied potential pulse is critical to proper electrode activation, whereas duration and total charge passed have minimal effects.
