Special Issue Information

Dear Colleagues,

The exploitation of optical fibers and plasmonic phenomena, such as surface plasmon resonance (SPR), localized surface plasmon resonance (LSPR) and hybrid modes, as detection principles, offers several advantages for sensing, such as high signal-to-noise ratio, small size, low cost, flexibility, label-free, real-time detection, and robustness. These sensors are widely applied in biomedicine, biomedical diagnostics, and environmental monitoring due to their high sensitivity and real‐time remote sensing capabilities. Several different optical fiber materials (silica, plastic fiber, etc.) and various optical fiber layouts (heterocore structures, lab-on-a-chip, D-shaped, U shaped, etc.) have been investigated. Furthermore, many methods have been used to enhance their performance, e.g., nanostructures, multilayers, and novel materials, such as MXene.

This Special Issue aims to highlight the recent advances and applications of optical fibers and SPR principles for chemical sensing. Authors are invited to submit work related to novel materials, sensor structures, mechanism studies, and applications. Both review articles and research papers are 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-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Chemosensors is an international peer-reviewed open access monthly journal published by MDPI.

In this work, we propose a hyperbolic metamaterials (HMMs)-based coreless fiber surface plasmon resonance (SPR) sensor.

In this work, we propose a hyperbolic metamaterials (HMMs)-based coreless fiber surface plasmon resonance (SPR) sensor. Leveraging the absence of a core in coreless fibers, the evanescent waves at the cladding–external solution interface couple more effectively into the solution, enabling surface plasmon resonance without any additional processing. To enhance sensitivity, we adopted a multimode–coreless–multimode (MCM) structure and grew layered hyperbolic metamaterials as the SPR-excitation-sensitive layer within the coreless region. Through finite element simulations, we optimized HMM parameters and fabricated high-performance HMM-SPR sensors. Test results demonstrate that the fabricated HMM-SPR sensor achieves an optimal refractive index sensitivity of 3703.33 nm/RIU, representing a 49.68% improvement over single-layer gold film SPR sensors. It successfully detects glucose solutions at varying concentrations with a sensitivity of 2671.25 nm/RIU. The high-sensitivity, structurally simple HMM-SPR sensor we proposed demonstrates broad application prospects in biosensing, environmental monitoring, food safety, and other fields. Full article
