Nanoparticles of noble metals showing localized surface plasmon resonances (LSPRs) have received considerable attention as materials that enhance light–matter coupling extraordinarily. The effect of near-field enhancement by LSPRs is known to be induced at the sharp tip of metallic nanostructures and/or the gap between adjacent nanostructures. Namely, spectral properties and near-field enhancement effects are highly dependent on the size, shape, and arrangement of metallic nanostructures. Therefore, well-defined metallic nanostructures have been fabricated by nano-processing methods to elucidate the essence of the resonance phenomenon, depending on the inter structure distance, and construct metallic nanostructures that show strong near-field enhancement. Such nano-engineered plasmonic nanomaterials have been applied to chemical and biosensors utilizing surface-enhanced Raman scattering (SERS) as well as LSPR sensors, light–energy conversion systems as light-harvesting optical antennae, surface plasmon amplification by stimulated emission of radiation (SPASER) for realizing lasers at the nanometer scale, nano-processing technologies, and so forth. Over the last decade, nano-engineered plasmonic nanomaterials have been employed for the study of various types of plasmonic coupling systems such as exciton–plasmon strong coupling, plasmon-hybridization, modal strong coupling, and/or plasmonic Fano resonances, and electromagnetically induced transparency (EIT), which are characteristics of the structure of Metamaterials. Recently, the structures have also received great interest as a metasurface for constructing significant optical elements. Thus, the nano-engineered plasmonic materials are studied in a wide variety of research fields. This Special Issue contains the above-mentioned research topics.

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. Nanomaterials is an international peer-reviewed open access monthly journal published by MDPI.
