Electrochemical Biosensing at the Frontier: Materials, Mechanisms, and Applications

Dear Colleagues

In recent years, advanced photoelectrochemical (PEC), electrochemiluminescence (ECL), and electrochemical (EC) technologies have made significant strides in enabling highly sensitive and selective detection across a wide range of applications. These emerging approaches hold great promise for tackling global challenges such as food safety, environmental pollution, and early disease diagnosis.

This Special Issue highlights recent advances in the design, synthesis, and application of novel materials and sensing platforms based on PEC, ECL, and EC techniques. Particular emphasis is placed on innovative strategies and multifunctional sensing systems for the rapid, accurate, and cost-effective detection of food contaminants (e.g., pesticides, antibiotics, and additives), environmental pollutants (e.g., heavy metals and endocrine-disrupting chemicals), and clinically relevant tumor biomarkers.

We welcome original research articles, reviews, and short communications that contribute to the understanding and development of these interdisciplinary sensing technologies. Submissions may cover, but are not limited to, the following topics:

• Photoelectrochemical sensors.
• Electrochemiluminescence sensors.
• Electrochemical sensors.
• Ratiometric, multi-channel, or visual sensor platforms.
• Porous materials (e.g., MOFs, COFs, and metal nanomaterials) in sensing applications.
• Signal amplification and conversion strategies.
• Portable and point-of-care detection systems.
• Sensing applications in food safety, environmental monitoring, and biomedical diagnostics.

The goal of this Special Issue is to bring together cutting-edge research and foster cross-disciplinary collaboration between material scientists, chemists, biotechnologists, and environmental/biomedical engineers to advance real-world sensing solutions.

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. Biosensors is an international peer-reviewed open access monthly 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 2200 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.
