Surface-Enhanced Raman Spectroscopy: New Perspectives and Future Directions

Dear Colleagues,

Surface-enhanced Raman spectroscopy (SERS) is a nanostructure-based vibrational spectroscopic technique playing a key role in analytical chemistry, spectroelectrochemistry, bioanalysis, microfluidics, food, and environmental analysis. To achive ultra-high sensitivity, this technique requires plasmonic nanostructures (Ag and Au) to enhance the Raman signals of adsorbed analytes. The sensitivity not only relies on the nature of nanostructures, but also on the morphology of SERS-active nanostructures, interparticle distance, and interaction with analyte molecules. Therefore, there are some bottleneck issues, including reproducibility, reusability, SERS substrates stability, and contamination, that are restricting the number of applications of this technique. Since its discovery, the SERS technique has made significant progress along with developments in nanoscience and nanotechnology. The aim of this Issue, “Surface-Enhanced Raman Spectroscopy: New Perspectives and Future Directions”, is to highlight recent developments in SERS substrates fabrication and novel applications in emerging fields. Researchers are invited to submit both review and research articles.

The Special Issue will offer a platform for the recent research activities in the following areas

1. Well-ordered novel SERS substrates
2. Alternative nanomaterials for SERS
3. SERS applications in energy devices
4. Bio-SERS
5. Microfluidic SERS
6. Role of machine learning and artificial intelligence in 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 250 words) can be sent to the Editorial Office for assessment.

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. Chemosensors 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 2000 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.
