Micro and Nano Optics for Advanced Sensing Technology

Dear Colleagues,

Detection of nanoscale objects with ultrahigh sensitivity is of critical importance in various fields including early-stage disease diagnosis, environmental monitoring, and process control of manufacturing. Over the past few years, various optical sensors featuring non-invasiveness, fast response, high sensitivity, and miniature footprints have been developed. The state-of-the art optical sensors realize a detection limit down to single nanoparticle/molecule employing diversified schemes such as scattering interferometry, plasmonic structures, microcavity, and nanofiber sensors. In particular, microcavity sensors attract much attention for their high-quality factors and small mode volumes enabling significant enhancement of light-matter interactions in confined space. Micro and nanofibers (MNFs) with subwavelength diameters offer engineerable waveguiding properties including optical confinement, fractional evanescent fields, and surface intensity, which is appealing for optical sensing on the micro and nano scales.

This Special Issue aims to attract original contributions in topics related to both experiment and theory regarding the measurement principles, detection techniques, and applications for micro and nano optical sensors and related technologies.

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. Crystals 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 2100 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.
