(Bio)sensors for Medical Diagnostics

Dear Colleagues,

(Bio)sensors have emerged as one of the most dynamic and transformative technologies in modern medical diagnostics. By combining biological recognition elements with highly sensitive physicochemical transducers, biosensors enable the rapid, accurate, and often real-time detection of clinically relevant biomarkers. Their development responds to an increasing global need for diagnostic methods that are not only precise but also minimally invasive, cost-effective, and accessible to diverse healthcare settings, from advanced hospitals to remote or resource-limited environments.

We are pleased to invite you to submit original research articles, systematic reviews, and other contributions to this Special Issue focused on the topics proposed below.

The importance of biosensors lies in their potential to fundamentally change how diseases are detected, monitored, and managed. They underpin many established diagnostic tools, as well as emerging technologies like wearable sensors, lab-on-a-chip platforms, and point-of-care testing devices for infectious diseases. Advances in nanotechnology, materials science, and biotechnology continue to expand their capabilities, enabling ultra-sensitivities, multiplex detection, and integration with digital health systems.

The goal of studying (bio)sensors for medical diagnostics is to understand their principles, evaluate their current applications, and explore future directions that could enhance patient outcomes and personalize healthcare.

In this Special Issue, original research articles and reviews are welcome. Research areas may include, but are not limited to, the following:

• Sensors and biosensors: Devices that convert biological or chemical interactions into measurable electrical or optical signals.
• Medical diagnostics: Techniques and tools used to identify diseases or health conditions accurately and efficiently.
• Biomarker detection: Detection of biological molecules that indicate normal or pathological processes in the body.
• Point-of-care testing: Rapid diagnostic testing performed near the patient for immediate clinical decisions.
• Lab-on-a-chip: Miniaturized devices that integrate laboratory functions onto a microchip for fast, low-sample-volume analysis.
• Wearable health technology: Portable devices that continuously track physiological parameters to support health monitoring.
• Nanotechnology: Use of nanoscale materials to improve detection, imaging, and targeted medical applications.
• Signal transduction: Process by which a sensor converts a biological event into a detectable and quantifiable signal.
• Early disease detection: Identification of illnesses at their earliest stages to improve outcomes and treatment success.
• Clinical monitoring: Ongoing tracking of vital signs and biomarkers to guide diagnosis, therapy, and patient management.

We look forward to receiving your contributions.

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. Diagnostics 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 2600 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.
