Description
The non-Faradaic impedance model is a physics-based model that describes the small-signal operation of an electrochemical sensor for detection of analyte molecules in a fluidic solution (for example, a solution containing DNA molecules). The physics-based model is described by an equivalent circuit with resistive (solution resistance) and capacitive (double layer capacitance and the cell capacitance) components. The model is validated against experimental data on a droplet based DNA biosensor.
The manual describes the general features of the model, the experimental data analysis and parameter extraction, and a demonstrative example of amplification of sensor signal.
In the future, the model will be generalized to include Faradaic electrodes and frequency dependent parasitic components.
