Nanostructured Materials Systems for Optical Sensing

Dear Colleagues,

Nanotechnology has demonstrated great potential in the preparation of new nanostructured materials with different properties, new functions, and added value. Numerous studies have been carried out with the aim to improve the properties and performance of optical functional materials through the application of nanocomposites, metallic nanoparticles or carbon materials.

Over the last decade, optical-sensing-based nanostructured materials have arisen as a key research topic in both fundamental and applied sciences. It is known that the optical response of nanostructured materials depends on their environment, namely, pressure, temperature, pH, and humidity, resulting in sensor materials with increased sensitivities, multiplexing capabilities, and high efficiency in detecting and monitoring chemical or biological molecules.

For example, the use of surface plasmon resonances in metallic nanostructured particles for surface enhanced Raman scattering (SERS) applications has gain special interest, in the last years. This is fundamentally due to two reasons: the technological evolution observed at the level of Raman's equipment and the development of techniques/methods to enhanced the molecular probe's signal using nanostructured materials. 

This Special Issue is addressed at all types of nanostructured materials that can be applied in optical sensing and detection of biomolecules, aiming to collect the latest trends and progress in the field of “Nanostructured Materials Systems for Optical Sensing”.

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. Sensors 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 2600 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.
