Abstract: | In this paper, we report a theoretical study exploring the stochastic signal from electrochemical detection toward the nanometer scale systems. By using a discrete simulation as well as a statistical theory, this work investigates the distribution of the capturing times for redox molecules that released at a given distance from an electrode. We find that the capturing times tend to distribute over a wider range with a larger distance between the molecule’s source and the electrode, and thus the corresponding electrochemical signal would be somewhat less repeatable. |
