For many decades, Raman spectroscopy has not been considered a useful analytical tool because of the very low efficiency of “normal” Raman scattering (the typical cross-section for Raman scattering is 11 and 8 orders of magnitude smaller than the typical cross-sections for absorption in ultraviolet and infrared). However, by utilizing special electromagnetic resonators constructed from plasmonic metals, the Raman scattering cross-sections could be increased by many orders of magnitude, making possible the observation of good-quality Raman spectra of even a single molecule. This effect is called SERS (surface-enhanced Raman scattering). Crucial to obtaining strong SERS signal is the application of an efficient SERS substrate. This Special Issue of Nanomaterials will attempt to cover the recent advances in nanomaterials for SERS spectroscopy, concerning not only their synthesis, but also simulations of the obtained local SERS enhancement factors and the applications of new nanomaterials in chemical and biochemical SERS analysis.

Abstract: Plasmon-coupled colloidal nano-assemblies with maximized surface-enhanced Raman scattering (SERS) are in high demand as plasmonic nano/bio/chemo sensors. So controlling the hot-spot density, precisely positioning the hot-spots for intensifying the plasmon coupling and specifically introducing the SERS molecule at that intense hot-spot is both eminent and challenging. We investigated their importance in nano-assemblies made of gold nanorod (AuNR) core and spherical nanoparticle (AuNP) satellites interconnected with ssDNA oligomers. Hot-spot positioning at the core NR tips were made possible by selectively burying the ssDNA at the lateral facets whereas retaining their hybridization and assembly potential at the tips. This strategy, with slight alterations, allowed us to form nano-assemblies with satellites only at the NR tips i.e., directional anisotropic nano-assemblies or satellites randomly positioned around the NR i.e., non-directional nano-assemblies. Directional nano-assemblies provided significantly improved plasmon coupling and significant SERS amplification of the interconnecting ssDNA, thus emphasizing the critical role of anisotropy, hot-spot positioning and SERS molecule positioning in nano-assemblies.
Title: Recent progress on the application of metal organic framework in surface enhanced Raman scattering

Abstract: In recent years, metal organic framework (MOF) based surface enhanced Raman scattering (SERS) has attracted much attention since MOF can largely improve the performance of SERS substrate toward target enrichment and signal enhancement. The combination of MOF and SERS improved the sensitivity of traditional SERS analysis and expended the application scope of SERS. The development and application of the MOF based SERS for the detection of chemical contaminants are discussed. The main advantages of using MOF based SERS are highlighted, as well as its limitations. Last but not least, promising future trends and application of MOF based SERS are also discussed.
