Surface-Enhanced Raman Spectroscopy for Sensing and Medical Diagnosis

Dear Colleagues,

Surface-enhanced Raman spectroscopy (SERS) is a vibrational-spectroscopy technique based on the intensity amplification of Raman scattering by metallic nanostructures with suitable plasmonic characteristics. Although SERS was initially limited to the analysis of dilute aqueous solutions of relatively simple systems such as small molecules or molecular ions, recent advances in nanotechnology, plasmonics, and photonics encouraged the application of SERS to more complex bio-systems such as macromolecules, cells, tissues, and biofluids. The high sensitivity and ability of SERS for qualitative and quantitative detection of one or more analytes indicate that this technique has outstanding prospects in sensing and medical diagnosis, as evidenced by its increasing applications in vivo. The aim of this Topical Collection is to offer an overview of recent advances in SERS technology and applications. With this aim, original research papers, as well as review articles, will be published to show the diversity of the new developments in this area and the wide dissemination of the SERS technique in medical diagnostics and sensing applications for environmental monitoring, agriculture, industry, food safety, security, and pharmaceutical research.

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. 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.
