Special Issue Information

Dear Colleagues,

Potentiometric sensors have the advantages of a small size, rapid response, ease of use, low cost, and resistance to color and turbid interferences. For these reasons, they have been extensively studied by researchers for many years.

Potentiometry has been injected with new vigor and has undergone a renaissance, with improvements in the detection limits and selectivity of ISEs, the introduction of new materials, and the use of nano-based materials and new sensing concepts, including sensor arrays, lab-on-a-chip, and paper-based sensors, as well as wearable sensors. These new breakthroughs encourage innovations in environmental, industrial, and biomedical sensing applications, including pollutants detection, (bio)markers, and specific analytes.

Therefore, this Special Issue aims to collate original research and review articles on the recent advances, technologies, solutions, applications, and new challenges in the field of potentiometric sensors for environmental, industrial, and biomedical applications.

In the realm of electrochemical nitrite detection, the potent oxidizing nature of nitrite typically necessitates operation at high detection potentials. However, this study introduces a novel approach to address this challenge by developing a highly sensitive electrochemical sensor with a low reduction detection potential. Specifically, a copper metal nanosheet/carbon paper sensitive electrode (Cu/CP) was fabricated using a one-step electrodeposition method, leveraging the catalytic reduction properties of copper’s high occupancy d-orbital. The Cu/CP sensor exhibited remarkable performance in nitrite detection, featuring a low detection potential of −0.05 V vs. Hg/HgO, a wide linear range of 10~1000 μM, an impressive detection limit of 0.079 μM (S/N = 3), and a high sensitivity of 2140 μA mM−1cm−2. These findings underscore the efficacy of electrochemical nitrite detection through catalytic reduction as a means to reduce the operational voltage of the sensor. By showcasing the successful implementation of this strategy, this work sets a valuable precedent for the advancement of electrochemical low-potential nitrite detection methodologies. Full article

Solid-contact ion-selective electrodes (SC-ISEs) have the advantages of easy miniaturization, even chip integration, easy carrying, strong stability, and more favorable detection in complex environments. They have been widely used in conjunction with portable, wearable, and intelligent detection devices, as well as in on-site analysis and timely monitoring in the fields of environment, industry, and medicine. This article provides a comprehensive review of the composition of sensors based on redox capacitive and double-layer capacitive SC-ISEs, as well as the ion–electron transduction mechanisms in the solid-contact (SC) layer, particularly focusing on strategies proposed in the past three years (since 2021) for optimizing the performance of SC-ISEs. These strategies include the construction of ion-selective membranes, SC layer, and conductive substrates. Finally, the future research direction and possibilities in this field are discussed and prospected. Full article
