Interests: microfluidics; optical sensors; biosensors; nanostructured metallic surfaces; surface-enhanced Raman spectroscopy (SERS) active substrates
Surface-enhanced Raman scattering/spectroscopy (SERS) has attracted increasing interest, both in terms of fundamental Physics/Chemistry and application in several fields, such as materials science, environmental sciences, sensors, biology, biophysics, and medicine. In fact, SERS can be exploited as a label-free detection method able to provide ultra-high sensitivity within biomolecular and chemical sensing. Typical SERS-active substrates are composed of noble metals (Au, Ag, Pt, etc.) in the form of roughened surfaces, nanoparticle aggregates, or arrayed elements.
Recently, a great deal of high quality research has been addressed to solid SERS nanostructured substrates, which can yield electromagnetic enhancement linked to surface plasmon resonances and/or chemical enhancement due to charge transfer processes. In addition to noble metals, semiconductors and transition metal-oxides have emerged as potential SERS-active substrates. The merging of electromagnetic and chemical enhancements can make SERS a powerful technique allowing vibrational spectra detection even from individual molecules. Moreover, microfluidic devices coupled with SERS detection methods are attracting great attention for the possibility to integrate in sensing platforms a biological or chemical protocol with a very sensitive technique, approaching a controlled analyte injection, a uniform molecular distribution and a reduced reagent volume.
This Special Issue aims to introduce recent progress in the synthesis and application of SERS-active substrates promoting a synergy of several complementary competences in the research community.

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. Materials 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 1600 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.

Abstract: Optical forces can be used to manipulate plasmonic nanoparticles  and create SERS-active hot spots in liquid . Biomolecules dispersed in liquid solutions can be detected using this approach with sensitivity down 100 nM . Here we apply this methodology to detect catalase and hemoglobin (Raman resonant molecules) reaching sensitivities of 10nM and 1 pM, respectively. We provide first evidence of quantitative detection of Bovine Serum Albumin, when stable aggregation conditions are met. Finally, we show that molecular specificity can be added to this methodology using nanoparticles functionalized with aptamers, providing first results on the detection of ocratoxin A, a fungal toxin occurring in food commodities and wine.
