Advanced Electrochemical Sensors for Environmental Monitoring

Dear Colleagues,

Electrochemical sensors are rapidly evolving into important tools for environmental monitoring, driven by advances in materials science and, more recently, artificial intelligence. Current research focuses on developing sensors with greater sensitivity, selectivity, stability, and the possibility of miniaturisation for the detection of trace levels of contaminants such as heavy metals, pesticides, pharmaceuticals, and microplastics in complex environmental matrices.  The field is rapidly progressing toward more robust, green, and intelligent sensing systems that can provide comprehensive, real-time insights into environmental quality. The integration of nanomaterials—including graphene, carbon nanotubes, and metal nanoparticles—has significantly enhanced electron transfer and surface reactivity, improving analytical performance.

This Special Issue welcomes contributions that explore novel sensing materials such as RuO₂-based electrodes and nanostructured composites, alongside machine learning techniques for signal processing. Emphasis will be placed on systems capable of real-time and in situ monitoring, autonomous calibration, and integration with wireless networks or IoT platforms. By bridging electrochemistry, environmental science, and computational intelligence, this issue aims to showcase how smart sensing technologies can improve detection accuracy and support data-driven environmental decision-making. Applications in water and air quality, soil contamination, and climate-related metrics will be central to this collection, offering a comprehensive view of the future of intelligent environmental sensing.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sensors is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
