Special Issue Information
Dear Colleagues,
In this Special Issue, we explore plasmonic sensors for a wide range of applications, as well as plasmonic sensing that is based on artificial intelligence.
Plasmonics is the study of the events that occur as a result of the oscillation of free electrons on the surface of a metal when the metal is subjected to the stimulation of light. This field has also achieved noteworthy and substantial breakthroughs in sensor technology over the last couple of decades. It is important to note that plasmonic sensors can be roughly divided into two types, surface-enhanced spectroscopic sensors and surface plasmon resonance (SPR) sensors, depending on the type of interaction that takes place between the outgoing photons and the plasmonic material. Surface-enhanced spectroscopic sensors measure light at the surface of an object, while surface plasmon resonance sensors measure light at the surface of an object.
In addition to this, there are normally two SPR modes that are investigated: localized surface plasmon resonance when the plasmons are closely bound to the surface of colloidal nanoparticles or other nanostructures, and propagating surface plasmon resonance at the flat dielectric–metal interface. Additionally, plasmon-based sensing has garnered a lot of interest in recent years due to the fact that it has a high sensing efficiency, low cost, small device footprint, stability, and a remarkable diversity, availability, and reusability of optically functional materials. The existing sensor technology is up against a number of substantial challenges, one of the most critical of which is the investigation of novel nanostructures with designer functions.
This Special Issue's coverage of the many plasmonic surface applications in optical sensing, such as biosensing, chemical sensing, gas sensing, and environmental monitoring, is one of its main goals.
This Special Issue is especially interested in (1) plasmonic nanomaterial characterization, (2) label free plasmonic sensing for chemical and biomaterials, (3) plasmonic surface for SPR/LSPR/SERS/TERS, and 4) computational and developing artificial intelligence based on plasmonic sensors. Researchers are encouraged to contribute to this Special Issue: full research papers, communications or reviews focusing on the keywords specified above are all acceptable forms of contribution.

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. Micromachines 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 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.
