Advances on Nanoplasmonic for Biosensing Applications

Dear Colleagues, 

Nanoplasmonics has received a lot of attention in the few last years. Nanoplasmonic materials are characterized by the localized surface plasmon resonance (LSPR) that represents the collective excitation of free electrons at a specific frequency as a result of the interaction of light with metallic nanoparticles or nanostructures. Their most exciting and distinctive feature is their ability to confine a large electromagnetic field in a nanometric volume surrounding the plasmonic nanostructure, also called the hotspot. This is very attractive for surface-enhanced applications such as surface-enhanced Raman scattering (SERS), surface-enhanced absorption (SEA), and surface-enhanced fluorescence (SEF). Both phenomena, LSPR and surface enhancement, depend on the electron density, environment or dielectric media, refractive index, size, and shape. The high sensitivity to the environment is ideal for sensing applications. Although there have been a lot of reports, challenges still exist in improving sensitivity, selectivity, and robustness. In this sense, this call is an invitation to send your recent results, both fundamental and applied, related to nanoplasmonics for biosensing for publication to pave the way for translation to clinical practice.

This Special Issue is focused on the recent progress in nanoplasmonics for nanosensors and SERS substrate-based biosensing design as a platform for biomedical applications. Topics include, but are not limited to, novel synthesis of nanoparticles; nanostructure design; new bioreceptors/biomarkers; functionalization strategies for specific and selective detection; and new configurations for enhancing sensitivity, including absorption, fluorescence, and scattering. Applications include single-molecule detection, pathogen detection, diagnostics, therapy monitoring, drug delivery, therapeutic drug monitoring, POC, and lab-on-a-chip devices.

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. Biosensors 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 2700 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.
