Chemical Sensors and Molecular Spectroscopy: Advanced Materials, Methods, and Applications

Dear Colleagues,

This, Special Issue, titled “Chemical Sensors and Molecular Spectroscopy: Advanced Materials, Methods, and Applications”, highlights the increased integration of chemical sensors and molecular spectroscopy. It demonstrates how spectroscopic techniques are driving substantial improvements in sensitivity, selectivity, and real-time analysis. Spectroscopic tools, including infrared (IR), Raman, surface-enhanced Raman scattering (SERS), ultraviolet-visible (UV-Vis), fluorescence, and related techniques, are increasingly integrated into chemical and biosensing platforms. These platforms provide deeper insights into sensor–analyte interactions and expand the capabilities of modern sensing systems. We are particularly interested in contributions that introduce novel sensing materials, innovative spectroscopic methods, integrated device architectures, or data-driven analytical strategies, including chemometrics, machine learning, and artificial intelligence. Studies may focus on fundamental mechanisms, experimental innovations, or practical applications. 

Topic of interest include, but are not limited to, the following: spectroscopic-guided sensor design; spectroscopic characterization of sensing materials and interfaces; IR, Raman, UV-Vis, fluorescence, NIR, THz, and high-resolution spectroscopic sensing; optical, electrochemical, plasmonic, and fiber-optic sensor platforms, biosensing and biomedical applications, nanomaterials and hybrid materials for sensing, and applications in environmental monitoring, biomedical diagnostics, industrial process control, and food quality assessment. Emerging sensing concepts that offer new molecular-level insights are also welcome.

This Special Issue aims to bring together interdisciplinary research linking chemical sensors with molecular spectroscopy and real-world applications across diverse fields. We invite both original research articles and comprehensive reviews that address current challenges and outline future directions of spectroscopic sensing 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. 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.
