“…The new synthesized thiomacrocyclic ionofore 4-phenyl-4-sulfide-11-(1-oxodecyl)-1,7-dithia-11-aza-4-phosphacyclotetradecane (cited in the text as compound IV as described in Figure 1) may also be used for sensing applications, acting as an ionophore of copper ions [10,11]. Its molecular structure allows forming Langmuir and LB films.…”

The new synthesized thiomacrocyclic ionophore 4-phenyl-4-sulfide-11-(1-oxodecyl)-1,7-dithia-11-aza-4-phosphacyclotetradecane has proven to form Langmuir and Langmuir-Blodgett (LB) films. This ionophore shows a large affinity for copper (II) ions. Then, the influence of the subphase composition on the surface pressure-area isotherms has been studied. The LB films have been observed by AFM and the effect of the subphase composition and the deposition surface pressure on the LB films is discussed. AFM image morphology has been correlated to the ionophore molecular structure. Surface pressure-area isotherms and AFM images show that the presence of copper(II) ions has an important role in the film structure.

“…12 With the added neutral carrier, the all-solid-state copper(II)-selective microelectrode exhibited a wide linear response range from 1 μM to 10 mM, a Nernstian slope of 29.5 mV·decade −1 , and a detection limit of 562 nM. Sensor response to the copper(II) was not impeded in the presence of common interfering species such as calcium and magnesium.…”

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

“…However, there were notable problems associated with the drift and overshoot of the standard potential, which have been mainly attributed to the lack of a thermodynamically welldefined electrochemical interface between the membrane and solid contact. To overcome these problems, adding an appropriate redox-active component in the membrane, such as a lipophilic silver complex [5], or use of conductive polymers as a contact between the solid support and membrane [6][7][8][9][10] was suggested.…”

The development of Cu(II) solid-contact ionselective electrodes, based on 1,2-di-(o-salicylaldiminophenylthio)ethane as a neutral carrier, is presented. For the electrodes construction, unmodified carbon ink (type 1 electrode) and polymer membrane-modified carbon ink (type 2 electrode) were used as solid support and transducer layer. Also, carbon ink composite polymer membrane electrode (type 3 electrode) was prepared. The analytical performance of the electrodes was evaluated with potentiometry, while bulk and interfacial electrode features were provided with electrochemical impedance spectroscopy. It is shown that modification of carbon ink with polymer membrane cocktail decreases the bulk contact resistance of the transducer layer and polymer membrane, thus enhancing the analytical performance of the electrode in terms of sensitivity, linear range, and stability of potential. The optimized electrodes of types 2 and 3 exhibit a wide linear range with detection limits of 1.8×10 −6 and 1.6×10 −6 M, respectively. They are suitable for determination of Cu 2+ in analytical measurements by direct potentiometry and in potentiometric titrations, within pH between 2.3 and 6.5. The electrodes are selective for Cu 2+ over a large number of tested transition and heavy metal ions.
