In the characterization of voltammetric sensors, researchers use Nyquist or Bode plots to study the stability and/or the electron transfer process. How can one interpret the resulting Nyquist plot? I will be grateful if anyone provide me with a paper or a review which summerizes this issue.

Hoping this will be helpful,

In attached you can find our paper. Is easy to interpret it. Just need to see the size of semicircle. If is larger mean the resistance of your material is higher.
