Dear Colleagues,

Rapid progress in nanophotonics and plasmonics has pushed forward the development of optical sensors with high sensitivity and high specificity for various detection targets and different applications. New physics and material/device design have enabled breakthroughs in the detection limit and detection functions. Miniaturization and high integration are becoming some of most important development trends of nanophotonic sensors. Biosensors is launching a Special Issue on Nano Optical Sensing Techniques, Devices, and Applications. Contributions may focus on the physics, fabrication and detection techniques, device design and applications of nanophotonic sensors in different forms. Tentative topics may include the following: new physics or photophysical mechanisms in nanophotonics or plasmonics for sensor applications; design and fabrication of nanophotonic structures or devices for sensor applications; new materials or structures for surface-enhanced Raman scattering spectroscopy; sensing techniques and devices for high-sensitivity and high-specificity detection of bio-reactions, bio-molecules and low-concentration molecules in the forms of gas, vapor, or liquids; optical fiber-based nanophotonic or plasmonic devices for remote sensing; microstructure fibers or photonic crystal fibers for gas and liquid sensing; on-chip integration of different forms of sensing devices; design and fabrication of micro-/nano-cavities as sensing devices; micro- or nano-scale light-driven actuators in different spectral bands with low thresholds and high sensitivity.

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.
