Impedance Spectroscopy and Biosensing
2007This chapter introduces the basic terms of impedance and the technique of impedance measurements. Furthermore, an overview of the application of this transduction method for analytical purposes will be given. Examples for combination with enzymes, antibodies, DNA but also for the analysis of living cells will be described.

Impedance spectroscopy (IS) is a general term that subsumes the small-signal measurement of the linear electrical response of a material of interest (including electrode effects) and the subsequent analysis of the response to yield useful information about the physicochemical properties of the system.

Assessment of cytotoxicity by impedance spectroscopy
Biosensors and Bioelectronics, 2007This paper describes a simple and convenient method to monitor on-line cell adhesion by electrical impedance measurements. Immortalized mouse fibroblasts, BALB/3T3, were cultured onto interdigitated electrode structures integrated into the bottom of an in-house fabricated device.

Binary signals in impedance spectroscopy
2012 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2012Using of binary waveforms in the fast impedance spectroscopy of biological objects is discussed in the paper. There is shown that the energy of binary waveforms can be concentrated onto selected separate frequencies. We can optimize the binary excitation waveform depending on the shape of frequency response of the impedance under study to maximize the ...

Electrochemical impedance spectroscopy of polyalkylterthiophenes
Electrochimica Acta, 1999The Electrochemical Impedance Spectroscopy investigation of two isomer polyalkylterthiophenes, namely poly-3′4′- and 33″-didodecylterthiophene was carried out at different stages of polymers oxidation. In the potential range 0.4⩽E⩽0.7 V vs Ag/AgNO3 the ionic resistance Rion associated with the insertion in the polymer structure of the doping species PF−

BioImpedance measurement is often assumed to be very straightforward, simply connect the sample or patient to the impedance analyzer and press the buttons. Unfortunately, if the researcher does not carefully study and plan the experimental set up, the experimental protocol and the fitting and interpretation of the data, the results tend to be largely ...

Electrical Impedance Spectroscopy of the Human Prostate
IEEE Transactions on Biomedical Engineering, 2007Tissue electrical impedance is a function of its architecture and has been used to differentiate normal and cancer tissues in a variety of organs including breast, cervix, skin, and bladder. This paper investigates the possibility of differentiating normal and malignant prostate tissue using bioimpedance spectra.

Assessment of cytotoxicity by emerging impedance spectroscopy
Toxicology and Applied Pharmacology, 2005An on-line and continuous technique based on electric cell substrate impedance sensing (ECIS) was developed for measuring the concentration and time response function of fibroblastic V79 cells exposed to toxicants. Mercury chloride (HgCl(2)), cadmium chloride (CdCl(2)), benzalkonium chloride (BAK), sodium arsenate (Na(2)HAsO(4)), and trinitrobenzene ...
