Non linear dielectric properties of microbiological suspensions at electrode-electrolyte interfaces

Abstract: Nonlinear properties of biological suspensions have been previously presented as a bulk phenomenon, however, some authors consider that they are generated at the electrode-electrolyte interface and are reflected as a bulk property phenomenon. They were mainly ascribed to the H+-ATPase present in the plasma membrane of these cells. In this paper, we describe the construction of a dual-cell nonlinear dielectric spectrometer. The system is applied to the study of interfaces with resting cell suspension… Show more

“…Details about the operation of the equipment have been published elsewhere [ 26 ]. Briefly, the computer generates a sinusoidal voltage signal which is applied through the SI1287 to the biological suspension contained in the cell, by means of two outer electrodes.…”

“…The responses were subtracted to correct the non-linear behavior of the interface. However, this became almost unpractical because these two interfaces were hardly similar (in their impedance response) even they were made with identical material and equally treated [ 26 ]. As an alternative, we decided to use the same interface repeatedly and test the biological response by using an inhibitor or activator of the enzyme, as it was also carried out by Woodward in his latest publications [ 18 , 19 ].…”

“…Multiple studies conducted since 1990 have examined the harmonics resulting from yeast membrane activities. They take away the spectrum of the ionic solution from the spectrum of the yeast suspension to get rid of the nonlinear features of the electrode–electrolyte interface from the data. On the other hand, some research employing distinct measuring devices or mathematical techniques has eliminated the disruptive influence of the interface and determined that the biological solution does not generate any quantifiable harmonic. , …”

“…Treo and co-workers did measurements with an improved nonlinear dielectric spectrometer and three different electrochemical cells (Treo et al, 2005;Treo and Felice, 2009). One of them was a replica of that used by Woodward and Kell, and the other two were three-and four-electrode cells respectively.…”
