Electrochemical Biosensors: Principle, Design and Applications

Dear Colleagues,

We are pleased to invite authors to contribute to this Special Issue, dedicated to exploring the latest innovations in electrochemical biosensors and emphasizing the role of nanomaterials and advanced characterization techniques in shaping the next generation of analytical devices. Recent advances in nanoscience have revolutionized biosensor design, enabling unprecedented levels of sensitivity, selectivity, and miniaturization. Graphene, carbon nanotubes, metallic nanoparticles (Au, Ag, Pt), and metal oxides (ZnO, TiO₂, MnO₂) have emerged as key materials offering large surface areas, enhanced conductivity, and catalytic activity. Moreover, hybrid and core–shell nanostructures are unlocking new possibilities for controlled electron transfer and interfacial stability in bioelectrochemical systems. Complementing these developments, state-of-the-art techniques such as TEM, XPS, AFM, and EIS provide deep insights into nanoscale morphology, composition, and charge-transfer processes. These breakthroughs have broadened the impact of biosensors across clinical diagnostics, environmental monitoring, and food safety, enabling real-time, point-of-care detection. This Special Issue welcomes original research, reviews, and perspectives addressing materials design, device integration, novel applications, and interdisciplinary approaches combining nanotechnology, microfluidics, and data analytics for smart and personalized health monitoring.

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. Applied Sciences 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 2400 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.
