“…These insulator layers are used in the field of effect transistor (ISFET) devices and electrolyte−insulator−semiconductor (EIS) structures in order to electronically record signals from cells or to detect biomolecular interactions at the solid liquid−interface. In literature, many studies were carried out using silicon dioxide and silicon nitride as transducer materials to make sensors and biosensors. − Besides, both insulator layers need chemical or physical treatments to get clean and highly active surfaces, aiming at enhancing the adhesion of chemical or biochemical species on the solid surface. Therefore, the surface properties of an affinity matrix are meant to explain its interactions with chemical or biological species.…”

In this report, we have introduced a revision of the chemical treatment influence on the surface thermodynamic properties of silicon dioxide (SiO(2)) and silicon nitride (Si(3)N(4)) solid thin layers. Some characterization techniques might be used to quantify the thermodynamic properties of solid surface and predict its ability in the adhesion phenomenon. In this work, we have used static and dynamic contact angle (CA) measurements to characterize both dioxide solid surfaces being treated by using the two procedures of cleaning and chemical activation. Qualitative and quantitative concepts of analysis, using the Van Oss approach, are based on the determination of dioxide surface hydrophilic and hydrophobic features and the thermodynamic parameters such as free energy, acid, base, and Lewis acid-base surface tension components. Electrochemical capacitance-potential measurements were carried out to study the reactivity of both silicon dioxide and silicon nitride surfaces for pH variation. Furthermore, the surface roughness of these insulators was examined by using the contact angle hysteresis (CAH) measurements and atomic force microscopy (AFM). It was concluded that CA technique can be used as a suitable and base method for the understanding of surface wettability and for the control of surface wetting behavior.

The aim of this work was to study the electrochemical behavior of gold electrode which was modified with p-tert-butylcalix[6]arene membrane and this in the presence of different nickel ions based concentrations in order to form a nickel electrochemical sensor. For that, impedance-spectroscopy characteristics have been investigated. The obtained results were then modeled by appropriate equivalent circuit aiming at elucidating the electrical properties of the modified gold transducer. A correlation between the present impedimetric results and previous potentiometric ones was achieved traducing then a fast ionic transfer.

In the present paper we report the characterization of platinum electrode modified with a polymeric membrane. The use of natural minerals such as phosphate rock (PR) from the mine of Djebel Onk (Algeria) was investigated as ionophore for Cd2+ ions detection. The impedance data were adjusted from 100 mHz to 100 kHz and at polarisation - 200 mV. The maximum exchange was obtained between pH 4 and 6. Low detection limit is about 10-5 M.
