Fast Scan Cyclic Voltammetry (FSCV)

Fast-scan cyclic voltammetry is an electroanalytical technique that applies dynamic potentials at an electrode surface to drive chemical reactions. Here, an example depicts the background-subtracted current collected from the oxidation of hydrogen peroxide (A). The resulting current is presented in the form of a cyclic voltammogram (CV), which serves to identify and the species present (B, C). Sub-second temporal resolution allows for chemical dynamics to be elucidated on a time scale commensurate with that of neuronal firing. The vast amount of data collected with this application is visualized with color plots (D).
