description | Microband electrode arrays are useful tools for the electrochemist, offering the enhanced sensitivity associated with microelectrodes but with a higher total current output. For optimum performance, the array may be designed such that space is used efficiently but the individual microbands behave as isolated electrodes on the time scale of the experiment. For a linear sweep experiment, the optimum specifications of a microband array depend on the scan rate used and the diffusion coefficient of the electroactive species. A two-dimensional simulation method is used to examine the nature of the diffusion to a regular array of microbands. Cyclic voltammetry of hexaammineruthenium(III)chloride is performed at a regularly spaced microband array to test the theory. © 2007 American Chemical Society. |
