Special Issue Information
Dear Colleagues,
Nanotechnology has revolutionized the field of electrochemical (bio)sensing, enhancing the capabilities and performance of devices significantly over recent decades. Currently, a diverse range of nanomaterials with various sizes, formats (e.g., thin films, spherical nanoparticles, and nanofibers), and compositions can be synthesized through well-established methodologies. These nanomaterials include the following:
(i) Carbon-based nanomaterials (e.g., carbon nanotubes (CNTs) and graphene oxide (GO)).
(ii) Noble metals and metal oxide NPs (e.g., Au, Ag, Cu, Pt, titanium dioxide, and zinc oxide).
(iii) Semiconductors materials (e.g., quantum dots (QDs)).
(iv) Hybrid composite nanomaterials.
These biocompatible nanostructures are highly appealing due to their exceptional surface area, mechanical strength, and electrocatalytic properties, which are particularly advantageous for the electroanalysis of biologically and chemically relevant (bio)molecules. Additionally, they can be integrated into biosensing platforms via straightforward adsorption or covalent immobilization techniques, ensuring stable and reproducible sensor fabrication. Alternatively, conducting surfaces can be modified with thin polymer films prepared through electrochemical polymerization. These films allow for fine-tuning of the metal–solution interface that can endow the sensor with specialized properties, such as antifouling, antibacterial, or self-cleaning capabilities. Furthermore, nanostructured materials may serve as a basis for the efficient coupling of affinity receptors, broadening their functional applications.
The practical applications of these high-performance electrochemical (bio)sensors are vast and varied, spanning environmental monitoring, food quality and safety assurance, precision agriculture, and advanced healthcare monitoring. These technologies are now being integrated into wearable, portable, and implantable bioanalytical systems, underscoring their relevance in modern-day innovations.

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.
