In this paper we demonstrate a quantitative way to measure the membrane potential of live cells by dielectric spectroscopy. We also show that the values of the membrane potential obtained using our technique are in good agreement with those obtained using traditional methods—voltage-sensitive dyes. The membrane potential is determined by fitting the experimental dielectric dispersion curves with the dispersion curves obtained from a theoretical model. Variations in the membrane potential were…

Erratum to: Towards the realization of label-free biosensors through impedance spectroscopy integrated with IDES technology
Preliminary efforts have shown that the configuration used could lead to a label-free non-invasive technique for biosensing and cellular behavior monitoring which might prove useful in investigation of the basic properties of cells and the effect of drugs by estimation of some fundamental properties and modification of the electrical characteristics of the device.

Extracellular fluid conductivity analysis by dielectric spectroscopy for in vitro determination of cortical tissue vitality.
This paper has used a bio-sensing method, dielectric spectroscopy (DS), which allows for the simultaneous measurement of the net efflux of all charged particles from cells by measuring extracellular conductivity and found that the changes in conductivity of theextracellular solutions were proportional to the severity of the pathological insult experienced by the brain tissue.
The voltage-dependence of MscL has dipolar and dielectric contributions and is governed by local intramembrane electric field
It is shown that besides protein dipoles, pore hydration can be affected by electric fields, and in patches, both WT MscL and its V23T mutant show a decrease in the tension midpoint with hyperpolarization.
