Optical Sensors for Biomedical Imaging and Diagnostics

Dear Colleagues,

Optical methods have revolutionized biomedical imaging and sensing by enabling diagnostic systems that are far less invasive than traditional approaches. Various optical sensor types have been developed, each relying on different physical mechanisms, such as chromophore fluorescence, scattering measurements, fiber-optic probes, spectroscopy, Raman scattering for molecular specificity, random laser emission in turbid media, emission from perovskite, and plasmonic resonance-enhanced signal amplification. This Special Issue aims to provide a comprehensive view of how optical sensors and imaging techniques can be optimized, validated, and translated into clinical practice. In particular, the aim is to cover the full spectrum of research in optical diagnostics, from sensor design and implementation to methods for interpreting data and images. Moreover, contributions addressing analytical modeling of light–tissue interactions, Monte Carlo-based numerical simulations of photon transport, and advanced artificial intelligence techniques for image analysis and decision support are especially welcome.

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. 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.
