Electrochemical Sensors and Biosensors in Food Analysis

Dear Colleagues,

Ensuring food safety, quality, and nutritional value is a global priority, as consumers and regulatory bodies demand rapid, reliable, and cost-effective methods for monitoring contaminants and key biomarkers. Traditional laboratory-based techniques such as chromatography and spectrometry, while highly accurate, are often labor-intensive, time-consuming, and unsuitable for on-site applications. This creates an urgent need for alternative analytical platforms that can deliver fast and sensitive results directly within food production and supply chains.

Electrochemical sensors and biosensors have emerged as versatile and powerful tools to address these challenges. Their advantages—high sensitivity, selectivity, miniaturization, and portability—make them particularly suitable for detecting a wide range of food-related targets, including pathogens, allergens, toxins, pesticides, and heavy metals. Advances in nanotechnology, surface modification, and bio-recognition elements have further improved detection performance, enabling multi-analyte analysis and integration into lab-on-a-chip systems. Moreover, coupling electrochemical sensing with digital technologies and artificial intelligence is paving the way for smart, real-time food monitoring solutions.

This Special Issue seeks to highlight recent innovations and applications of electrochemical sensors and biosensors in food analysis, from toxicological assessment to nutritional monitoring. The topic aligns closely with the scope of Chemosensors, emphasizing novel device development, interdisciplinary approaches, and real-world impacts on food safety and public health.

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 100 words) can be sent to the Editorial Office for announcement on this website.

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. Chemosensors 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 2000 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.
