Special Issue Information

Dear Colleagues,

We would like to invite you to submit your contribution to the Special Issue on “Advanced in Electrochemical Sensing and Analysis” in Chemosensors.

This Special Issue is dedicated to exploring recent advances and existing challenges in the field of electrochemical sensing and analysis. Electrochemical sensing and analysis have a wide range of applications, and innovations in this field are of great value in food quality monitoring, health diagnostics, environment, chemical process control, and forensic analysis. However, the rapid development in the field of electrochemistry relies on the sensitivity, selectivity, and stability of electrochemical sensing or analysis systems. Challenges in this area may be new sensitive materials, surface treatments, innovative processes, etc., and the innovations in these aspects will improve the parameters of existing sensors or new sensor systems.

The Special Issue will cover, but is not limited to, the following topics:

  • Advances in electrochemical detection (potentiometry, amperometry, voltammetry, electrochemical impedance spectroscopy);
  • Novel concepts’ electrochemical sensors;
  • Preparation, modification, and characterization of advanced electrodes;
  • Molecular recognition with electrochemical detection;
  • Trends in analytical electrochemistry;
  • Electrochemical sensors and sensor-array chemometrics;
  • Applied analytical electrochemistry.

The aim of this Special Issue is to identify recent advances and novel trends that lead to improvement of the characteristics of electrochemical sensors critical for their application. Studies concerning the electrochemical detection of multiple applications will be presented. This Special Issue opens the possibility for contributions from the researcher community including the younger generation working in the field of electrochemical detection.

On behalf of the Guest Editor and the Editor-in Chief, we encourage you to submit your work to this Special Issue.

Traditional working electrodes are not sufficient to realize the low detection limit and wide detection range necessary for the detection of heavy metals. In this study, a microelectrode array electrode was proposed using a design scheme based on microelectromechanical systems that was optimized with finite element software. The working electrode adopted an innovative composite structure to realize the integrated design of the working and counter electrodes, which improved the system integration. Performance tests showed that the electrode realized the quantitative analysis of Cd(II), Pb(II), and Cu(II) with a low detection limit (0.1 μg/L) and a wide detection range (0.1–3000 μg/L). The electrode successfully measured the lead and copper ion concentrations in the Sanya River, including both seawater and freshwater environments. The experimental results demonstrate that the electrode exhibits excellent adaptability to environmental conditions and can be potentially applied for technical support in environmental monitoring and sewage treatment.
