Special Issue Information
Dear Colleagues,
Optical biosensors gain huge interest among researchers due to their wide range of applications in healthcare and environmental monitoring. The optical biosensor utilizes the property of propagated light in order to detect and analyze biological and chemical interactions; therefore, it provides several benefits including exceptional in situ monitoring, high sensitivity, and rapid response time. Optical biosensors generally involve the study of light–matter interaction for target-specific detection. This interaction leads to a change in the property of the measurable optical signal, which can be correlated to the concentration or presence of the analytes. The optical signals through the optical devices can be generated via several mechanisms, such as variation in fluorescence, absorbance, interferometry, evanescent wave coupling, and surface plasmon resonance. This Special Issue is dedicated to exploring the groundbreaking technologies and applications of optical biosensors. The applications of optical biosensors are vast and diverse. These biosensors play a crucial role in the detection of several diseases at an early stage by detecting pathogens, biomarkers, and genetic disorders. Optical biosensors are also useful in other sectors such as environmental sensing, food safety monitoring, and drug delivery. This Special Issue highlights the most recent development in the area of optical biosensors, including cutting-edge fabrication techniques, innovative sensing configurations, and the integration of optical devices with novel sensing materials. This Special Issue includes studies that demonstrate successful implementations of optical biosensors in these domains, emphasizing their remarkable accuracy, specificity, and potential for high-throughput analysis. The articles featured in this Special Issue explore various sensing devices and novel configurations, emphasizing their potential to achieve high sensitivity and a rapid response time.

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.
