Plasmonic Sensors: Advances and Applications

Dear Colleagues,

Over the past three decades, we have witnessed intense research and development activity in the field of plasmonic sensors, driven by their unique characteristics of sub-wavelength confinement and strong light–matter interaction offered by the profound exposure of plasmonic modes to the ambient environment. This unmatched feature makes plasmonic sensors extremely sensitive to local refractive index changes, establishing them as a leading solution in optical sensing. Plasmonic sensors rely on the excitation of either propagating or localized plasmonic modes, leading to various types of plasmonic sensing devices including SPR sensors, integrated all-plasmonic or plasmo-photonic sensors and nanoplasmonic sensors. This versatility enables the design of novel devices with extraordinary performance, paving the way for breakthroughs in both fundamental research and practical applications.

Ιn this Special Issue, we aim to highlight recent advances in plasmonic sensor configurations, addressing key challenges in enhancing sensitivity, limit of detection, stability, and multiplexed detection while exploring their application in real world scenarios such as medical diagnostics, pharmaceuticals, life science research, environmental monitoring, and food safety.

We welcome original research articles, both theoretical and experimental, as well as comprehensive reviews. Research areas may include, but are not limited to, the following:

• Surface plasmon resonance (SPR) sensors;
• Localized surface plasmon resonance (LSPR) sensors;
• Integrated plasmonic sensors;
• Hybrid photonic-plasmonic sensors;
• Advanced fabrication techniques for plasmonic sensors;  
• Biosensing applications for healthcare and point-of-care diagnostics;
• Environmental and chemical sensing;
• Food safety applications;
• Gas sensing;
• Temperature sensing.

We look forward to receiving your valuable contributions.

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. Photonics 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 2400 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.
