Abstract

•High-frequency impedance is used to characterize nanochannel dielectric properties.•A procedure was proposed for determining conductance and capacitance of a nanochannel.•The simulated results highlight a conductance law according to two regimes.•We observed a constant phase element behaviour originating from nanochannel geometry.

High-frequency electric impedance spectroscopy is used to characterize the dielectric properties of a single nanochannel in a micro/nanofluidic device. The simulated electric impedance results lead to the determination of two conductance regimes, a non-ideal capacitance and its surface charge.
