Special Issue "Novel Spectroscopy Applications in Food Detection"
Deadline for manuscript submissions: 10 March 2022.
The Raman spectroscopy (RS) technique relies on the irradiation of a sample by means of an intense laser radiation in the range of the visible, near-infrared or ultraviolet, and on the measurement of the electrons inelastically scattered from the sample itself. As a result, a spectrum (the “Raman spectrum”) is obtained whose shape is strongly dependent on the chemical properties of the analyzed sample and that can be considered as its specific “chemical fingerprint”, allowing the unambiguous identification of the analyzed molecules.
RS has multiple advantages that make it an outstanding candidate for the analysis of many samples, either in solid, liquid or gaseous state. Unlike infrared spectroscopy, Raman analysis is minimally affected by the water content of the sample, and it is therefore suitable for analysis in aqueous matrices, typical of many biological samples. Moreover, RS, if compared to other established and sensitive chemical techniques, is nondestructive, very rapid, and economic. Furthermore, portable instruments are available, thus enabling in situ analysis. Thanks to these properties, RS has gained a prominent role in many research fields, such as fundamental physics and chemistry, material sciences and nanotechnologies, and art, biological, medical, and pharmacological sciences.
This Special Issue aims at gathering prominent scientific works focused on the development of novel Raman-based approaches for rapid detection of analytes in a wide range of research areas, from food safety and traceability to biomedical application and nanotechnologies. We expect contributions concerning RS and its various declinations, such as surface-enhanced Raman (SERS), tip-enhanced Raman (TERS), hyper-Raman, coherent anti-stokes Raman (CARS), and stimulated Raman (SRS). Manuscripts aimed at these goals will be considered for publication.

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 papers will be 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 2300 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.
