Special Issue Information
Dear Colleagues,
Nanomaterials have excellent performances in catalysis, optics, electricity, magnetism, chemistry and superconduction due to their special properties, such as their interfacial, quantum size and macroscopic quantum tunneling effects. Metal nanomaterials with excellent plasmonic properties have been widely used in spectrum technology for chemical analysis and molecular detection.
Plasmonic-based spectroscopy is a promising technique to probe and identify molecules and chemicals. Amplified by plasmonic nanostructured metals, the signal intensity of a target can be dramatically improved. Surface-Enhanced Raman Scattering (SERS) can be dramatically improved by a factor of up to 10 orders of magnitude with nanostructured metals that possess electromagnetic “hot spots” at the sharp edges and nanogaps between nearby metals. Accordingly, it becomes possible to detect and distinguish the spectroscopic signature of a single molecule by SERS, and developing a novel metal nanostructure with a high density of “hot spots” has been a recent topic of intense discussion. Additionally, surface plasmon enhancement has been used in fluorescence, infrared and THz spectroscopy, and demonstrates high potential for trace detection applications.
We invite researchers to contribute original and review articles regarding the metal nanomaterials. Potential topics include, but are not limited to, the following: synthesis, modification, and functionalization of metal nanomaterials; application of metal nanomaterials as light concentrators, plasmonic substrates, optical sensors and signal amplifiers; in vitro and in vivo spectroscopy studies of chemicals and molecules with metal nanomaterials.

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. Nanomaterials 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 2400 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.
