“…The pin with the Ag/AgCl layer selected to be used as reference electrode (RE) was covered with Nafion to increase the stability of the reference signal and to prevent a reaction between the Ag/AgCl surface and the analyte. After the coverage with Nafion membrane, the electrodes were left for 48 h under vacuum and then dried at 100 °C for 1 h [16]. The electrodes used as working electrodes (WEs) were covered with pH ISE membranes on Ag/AgCl surface or nitrate ISE membranes on carbon surface and left to dry overnight at room temperature for testing the performances of the Ag/AgCl and carbon surfaces as transducer layers.…”

Here we have developed a simple method for the fabrication of disposable implantable all-solid-state ion-selective electrodes (ISE) in an array format without using complex fabrication equipment or clean room facilities. The electrodes were designed in a needle shape instead of planar electrodes for a full contact with the tissue. The needle-shape platform comprises 12 metallic pins which were functionalized with conductive inks and ISE membranes. The modified microelectrodes were characterized with cyclic voltammetry, scanning electron microscope (SEM), and optical interferometry. The surface area and roughness factor of each microelectrode were determined and reproducible values were obtained for all the microelectrodes on the array. In this work, the microelectrodes were modified with membranes for the detection of pH and nitrate ions to prove the reliability of the fabricated sensor array platform adapted to an endoscope.

“…In their publication, Blaz et al [48] listed the different types of existing reference electrodes. However, the interest in conducting polymer-based all-solid-state reference electrodes—equitransferent salts dispersed in polymer or compensated cationic and anionic response in polymer—grows each day [48,49,50]. …”

We present an innovative electrochemical probe for the monitoring of pH, redox potential and conductivity in near-field rocks of deep geological radioactive waste repositories. The probe is composed of a monocrystalline antimony electrode for pH sensing, four AgCl/Ag-based reference or Cl− selective electrodes, one Ag2S/Ag-based reference or S2− selective electrode, as well as four platinum electrodes, a gold electrode and a glassy-carbon electrode for redox potential measurements. Galvanostatic electrochemistry impedance spectroscopy using AgCl/Ag-based and platinum electrodes measure conductivity. The use of such a multi-parameter probe provides redundant information, based as it is on the simultaneous behaviour under identical conditions of different electrodes of the same material, as well as on that of electrodes made of different materials. This identifies the changes in physical and chemical parameters in a solution, as well as the redox reactions controlling the measured potential, both in the solution and/or at the electrode/solution interface. Understanding the electrochemical behaviour of selected materials thus is a key point of our research, as provides the basis for constructing the abacuses needed for developing robust and reliable field sensors.

This review covers publications related to electrochemical sensors that appeared in print during the years 2006 and 2007. The focus of the review is on the development of electrochemical sensing principles including potentiometric and chronopotentiometric sensors, reference electrodes, voltammetric sensors, and electrochemical biosensors.References were collected by searching electrochemical sensor-related work using ACS SciFinder and ISI Science Citation Index. In addition, the tables of contents of several analytical journals were reviewed manually to identify relevant articles. Only original and review articles written in English were considered. Patents, book chapters or book series, and conference proceedings or abstracts were not considered for this review. The number of references was limited to 200 and as a result only a fraction of relevant work is covered. Specifically, the review was written to focus on fundamental aspects of electrochemical sensor research emphasizing new chemical concepts and not simply the application of electrochemical sensors. On the basis of these guidelines, several hybrid systems whereby electrochemical detection schemes were combined with a separation technique such as microdialysis, electrophoresis, chromatography, and lab-on-a-chip were not included in this review.We ask that our readers note that our review is not a comprehensive coverage of the above topics, but rather a snapshot of research conducted over the past two years. Obviously, electrochemical sensor research is still expanding and of interest to a number of disciplines beyond traditional chemistry. As such, it was not possible to cover all manuscripts published. We apologize to the authors of manuscripts that were not included in this review. POTENTIOMETRIC SENSORS ReviewsBakker and Pretsch published a broad review on modern potentiometry describing techniques for improving sensor performance, miniaturizing sensor platforms, and expanding the application of potentiometric sensors for environmental trace analysis and biosensing (98 citations). 1 Likewise, Pretsch provided a general overview on ion-selective electrodes (ISEs) focusing on improving detection limits and understanding non-classical (i.e., non-equilibrium) potentiometry for monitoring clinical relevant polyions such as heparin and protamine (81 citations). 2 De Marco et al. reviewed ISE methodologies for the analysis of trace metals and anions (e.g., F − , CN − , NO 3 − , NO 2 − , and Cl − ) in environmental samples. 3
