title = "Dimensional analysis to distinguish diffusion-limited and charge-transfer reaction-limited processes of fabricated impedimetric micro electrochemical sensors to detect hydrogn and ammonium ions",
abstract = "Dimensional analysis was applied to systematically study the diffusion-limited (DL) and chargetransfer reaction-limited (CRL) processes in Micro electrochemical sensors (MECSs). The electrochemical impedance spectroscopy (EIS) for MECS to detect hydrogen and ammonium ions was fitted with the equivalent circuit model (ECM). With the help of Buckingham Pi Theorem, two dimensionless parameters: normalized impedance and reaction-diffusion-frequency were identified to distinguish these two processes. The results showed that these two parameters can be applied not only in our fabricated MECSs for detecting hydrogen and ammonium ions, but also in other reported relevant works for detecting copper ions and DNA molecules.",
