Special Issue Information
Dear Colleagues,
Optical sensing is revolutionizing biomedical applications by offering significant advantages over conventional analytical techniques. These sensors enable the direct, real-time, and label-free detection of biological and chemical substances, making them highly effective for diagnostics, environmental monitoring, and food safety. Over the years, optical biosensors have been transforming the way we detect and analyze biological and chemical substances, offering fast, accurate, and real-time monitoring across various fields. By harnessing light-based techniques such as fluorescence, guided-mode resonance (GMR), localized surface plasmon resonance (LSPR), and photonic crystals, these sensors provide high sensitivity and specificity without requiring complex sample preparation.
This Special Issue explores the latest advancements in optical biosensor technology, covering a wide range of innovations, from optical fibers to plasmonic biosensors, showcasing enhanced sensitivity and detection capabilities. The Special Issue also examines the integration of biosensors with cutting-edge technologies like microfluidics, lab-on-a-chip systems, and wearable diagnostics, pushing the boundaries of personalized medicine and point-of-care testing.
By bringing together researchers from optics, photonics, biology, and medicine, this Special Issue fosters interdisciplinary collaboration and showcases how optical biosensors are shaping the future of diagnostics and analytical science. As these technologies continue to evolve, they hold immense potential to revolutionize healthcare, drug discovery, and environmental 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. Sensors 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.
