Optical Nanobiosensors

Dear Colleagues,

Optical biosensors are emerging as a robust and widely adopted platform for disease diagnosis due to their high sensitivity, reusability, and ultrafast detection capabilities. These features enable precise and reliable analysis across a wide range of biological targets.

Optical nanobiosensors represent an advanced class of biosensing platforms developed through the integration of nanotechnology with optical bio-detection. Nanoscale-based sensors provide larger surface areas, unique optical properties, and multifunctionalities, resulting in increased sensitivity and faster reaction times.

Numerous optical nanobiosensors, including plasmonic sensors, fluorescence-based probes, and metasurface-based devices, have been developed to overcome the limitations of conventional bioanalytical methods in terms of sensitivity, throughput, ease of use, and miniaturization. These technologies offer significant potential for early disease diagnosis and personalized therapeutic strategies.

This Special Issue welcomes original research articles, in-depth reviews, communications, and perspectives covering all aspects of optical nanobiosensors, including their materials, underlying mechanisms, sensing techniques, and translation to diverse applications. Topics of interest include, but are not limited to, the following: nanophotonic devices, refractometric affinity biosensing, fluorescence-based biosensing, operational mechanisms, nanoparticles, nano arrays, nanophotonic crystals, plasmonics, metasurfaces, biomarker detection, point-of-care testing, lab-on-chip platforms, microfluidic devices, and biochips.

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. Biosensors 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 2200 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.
