Molecularly imprinted electrochemical impedance sensor for sensitive dibutyl phthalate (DBP) determination

Sensors and Actuators B: Chemical, 2019
An efficient approach that integrates a molecularly imprinted conducting polymer, polypyrrole (PPY) with a sensitive electrochemical impedance sensing platform for the quantification of dibutyl phthalate (DBP) was presented.

Dynamic Electrochemical Impedance Spectroscopy

ECS Transactions, 2009
The hardware and software for a dynamic electrochemical impedance spectroscopy system are described. The applied waveform is a continuous computer-generated multisine waveform added to a potential sweep. A fast potentiostat applies the potential signal and the impedance is derived from the Fourier transforms of the measured current and potential ...

Electrochemical Impedance Spectroscopy

2012
Electrochemical impedance spectroscopy (EIS) is a method to study the characteristics of organic and inorganic materials, based on their passive electrical properties, determined by the observation of the tissue electrical response to the passage of external electrical energy.

Electrochemical Impedance Spectroscopy of protective coatings

Materials and Corrosion, 1985
AbstractElectrochemical impedance spectroscopy (EIS) carried out over a wide frequency range (105 to 10−2 Hz) allows us to obtain mechanistic information concerning corrosion protection by coatings. Examples are given for polymer coatings on an Al alloy as a function of surface petreatment and for anodized Al alloys.

Electrochemical impedance spectroscopy of polynucleotide adsorption

Bioelectrochemistry, 2002
The dependence of the impedance of the electrode double layer of mercury electrode on frequency around the potentials of the tensammetric peaks of single-stranded and double-helical polynucleotides and DNA was studied. From the frequency dependence of the impedance of the electrode double layer represented in a complex plane impedance plot, the ...
