Special Issue Information
Dear Colleagues,
All scholarly research involves making some kind of measurement. This requires scientific instruments that detect and quantify the material properties of a sample being examined (or some change in them). If the sample is biological, then biosensors are utilized, which have an extensive history. There is great variety in terms of their operating principle, sensitivity, and other important properties, depending on the available technology.
One of the most accurate of these sensors are optical biosensors, which detect and quantify the biological characteristics of a sample by measuring its optical properties. The revolutionary development of electronics (for example, in optical detectors and digital signal processing) and the worldwide “march” of laser have introduced intermetric accuracy and high-speed measurements into the field of optical biosensors. In general, advances in sensors follow technological innovations almost immediately, including the use of new materials (materials science) and new computer algorithms (signal processing and artificial intelligence). In many cases, these new methods are alternatives to traditional methods (such as ELISA); this is not because established methods are less accurate and applicable but because they unfamiliar to some scientists.
It is crucial to remember that even traditional methods were once new to scientists of their era.
It is the aspiration of every researcher that the results of their work will one day be widely applicable in laboratories or even in everyday life.
To support scholars in achieving this objective, we are launching this Special Issue to provide a platform to publish the latest results and developments in optical biosensors. It will present the most recent technological developments, including the use of new materials, in optical biosensors.

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.
