Special Issue Information
Dear Colleagues,
Surface enhanced Raman scattering (SERS) has been emerging as an important tool for the high sensitivity detection of analytes in diverse fields, such as food chemistry (i.e., additives and contaminants), security (i.e., warfare agents and explosives), forensic science (i.e., gunshot residues and drugs), and biomedicine (i.e., cellular functions and bacteria). Its advantage lies in the combination of the intrinsic recognition capabilities of Raman with the strong signal enhancement brought about by suitable nanostructured substrates. Several aspects of SERS are currently under investigation in the scientific community, ranging from fundamental issues on the physical origin of the SERS enhancement, to the implementation of this spectroscopy technique in practical applications; in particular, the design and fabrication of novel substrates, reproducible, highly enhancing and possibly mass producible, is a crucial point for a widespread diffusion of SERS.
This issue focuses on the study and fabrication of novel SERS substrates. The range of possible topics is very wide. Some examples could be the preparation of nanoparticles with optimal shapes for SERS, new strategies for assembling hot-spots (in solution or on solid surfaces), the development of cheap and large-scale fabrication processes, the design of SERS labels, the use of alternative materials in addition to the traditional noble metals (i.e., dielectrics, semiconductors or graphene), structure–property investigations of the relation between the morphology and the near/far field properties, the combination of substrates with separation and capturing techniques, etc.

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. Applied Sciences 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.
