Sensing Estrogen with Electrochemical Impedance Spectroscopy

This study demonstrates the application feasibility of electrochemical impedance spectroscopy (EIS) in measuring estrogen (17β-estradiol) in gas phase. The present biosensor gives a linear response (R2 = 0.999) for 17β-estradiol vapor concentration from 3.7 ng/L to 3.7 × 10-4 ng/L with a limit of detection (3.7 × 10-4 ng/L). The results show that the fabricated biosensor demonstrates better det...

An integrated approach to electrochemical impedance spectroscopy

A philosophy for electrochemical impedance spectroscopy is presented which integrates experimental observation, model development, and error analysis. This approach is differentiated from the usual sequential model development for given impedance spectra by its emphasis on obtaining supporting observations to guide model selection, use of error analysis to guide regression strategies and experi...

Reducing Impedance Fluctuation by Electrode Structure for Electrochemical Impedance Spectroscopy

In this paper, we investigated the electrode structure of the electrical bio-sensor to reduce impedance measurement fluctuation. Five pairs of the same electrodes were formed on the PCB substrate, and a fluidic channel was constructed with a double-sided tape and polycarbonate cover so that all the electrodes had the same reagent distribution. In order to find an electrode structure with little...

Evaluation of Organic Coatings with Electrochemical Impedance Spectroscopy

This seemingly basic equation actually hides some sophisticated assumptions and concepts. First, it applies only to the time varying, alternating, or ac, components of the current and voltage. Secondly, it is not sufficient to just tell how big the voltage and current signals are, we must also say how they are related in time, since they are both timevarying, ac quantities. Finally, the sizeand...

Real-time monitoring primary cardiomyocyte adhesion based on electrochemical impedance spectroscopy and electrical cell-substrate impedance sensing.

The cell-substrate distance is a direct indicator of cell adhesion to extracellular matrix which is indispensable in cell culture. A real-time monitoring approach can provide a detailed profile of cell adhesion, so that enables the detecting of adhesion-related cell behavior. In this work, we report a novel real-time impedance-based method to record the adhesion profile of cardiomyocyte, overco...
