Electrochemical Sensors in Bioanalytical Chemistry

Dear Colleagues,

Electrochemical sensors have emerged as sensitive and selective devices for targeted and multiplexed analyses in complex systems and found applications in multidisciplinary fields including, among others, medicine, agri-food, and environmental science. The analytical robustness, reliability, cost-effectiveness, integrability, and versatility of heterogeneous and homogeneous configurations account for the widespread fabrication and successful exploitation of electrochemical sensors achieved during the last few decades. Furthermore, the intrinsic features of electrochemical methods made downscaling of the measuring systems possible, giving rise to the development of lab-on-chips, point-of-care testing, and wearable devices emerging as breakthrough technologies in translational research.

Electrochemical transducers are at the core of electrochemical sensors and convert chemical information into measurable electrical signals (such as current, voltage, charge, and impedance) in a proportional manner to the analyte’s concentration. The intervention of nanomaterials, nanocomposites and conducting polymers in electrochemical sensor build-up, along with improvements in miniaturization techniques, and engineering of chemical and biological matter contributed to the development of sensors with unprecedentedly high sensitivity and selectivity parameters.

This Special Issue covers the latest advances in electrochemical sensors development, focusing on all aspects of design, fabrication, and implementation strategies exploiting functional materials and natural or biomimetic materials.

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 2700 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.
