Dear Colleagues,

Vibrational spectroscopy methods have found many applications in science, engineering, medicine, and other spheres of human life. In the past few decades, the tools for performing molecular analysis using infrared (IR) and Raman spectroscopy have improved so much that it has become possible to detect target single molecules and visualize them in complex biological objects. One of the decisive roles in achieving such amazing results has been played by the combination of nanomaterials that facilitate enhancing IR absorption and Raman scattering, spectrometers, confocal, and probe microscopes. This has led to the development of unique precision techniques such as tip-enhanced Raman scattering (TERS), surface-enhanced Raman scattering (SERS), surface-enhanced IR absorption (SEIRA), and surface-enhanced coherent anti-Stokes Raman scattering (SECARS), which now have tangible prospects to be widely implemented for accurate and reproducible non-contact measurements. This Special Issue aims to publish new research and state-of-the-art applications in all types of nanomaterials for TERS, SERS, SEIRA, and SECARS, including but not limited to the design, simulation, and engineering of metallic, dielectric, and hybrid nanostructures to improve molecular analysis performances, such as selectivity, reproducibility, accuracy, availability, and biosafety. It is my pleasure to encourage both theoretical and empirical work in this ever-expanding and exciting field of science and technology.

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 100 words) can be sent to the Editorial Office for announcement on this website.

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. Biosensors 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 2200 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.
