abstract = {We simulate the amperometric response time of an
interdigitated electrode array with respect to reversible
adsorption of redox active molecules at the electrode
surface. When neighboring electrodes are biased to
potentials below and above the redox potential of the
species under investigation, molecules can participate in
repetitive reactions leading to an amplification of the
Faradaic current. During collisions between molecules and
electrodes, the molecules may undergo reversible adsorption.
We simulate the behavior of this redox cycling process by
using a discrete random walk model, which mimics the
diffusive pathway of the molecules. Adsorption probabilities
are implemented via the boundary conditions at the
electrodes. Using this simulation, we investigate the effect
of reversible adsorption on the response time of the
interdigitated electrode array.},
