Nanomaterials for Surface Enhanced Raman Spectroscopy

Dear Colleagues,

For many decades, Raman spectroscopy has not been considered a useful analytical tool because of the very low efficiency of “normal” Raman scattering (the typical cross-section for Raman scattering is 11 and 8 orders of magnitude smaller than the typical cross-sections for absorption in ultraviolet and infrared). However, by utilizing special electromagnetic resonators constructed from plasmonic metals, the Raman scattering cross-sections could be increased by many orders of magnitude, making possible the observation of good-quality Raman spectra of even a single molecule. This effect is called SERS (surface-enhanced Raman scattering). Crucial to obtaining strong SERS signal is the application of an efficient SERS substrate. This Special Issue of Nanomaterials will attempt to cover the recent advances in nanomaterials for SERS spectroscopy, concerning not only their synthesis, but also simulations of the obtained local SERS enhancement factors and the applications of new nanomaterials in chemical and biochemical SERS analysis.

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. Nanomaterials 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 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.
