Summary: We demonstrate a significant enhancement of the Faraday effect in a magnetoplasmonic nanocomposite based on Au nanoparticles and a bismuth-substituted iron-garnet film. The Faraday effect is enhanced by more than 20 times compared to the same bare magnetic film due to the excitation of localized plasmon resonances in the Au nanoparticles.

Summary: This study discusses the influence of controllable carriers on localized surface plasmon resonance (LSPR) in (Ag)x(MoO3)y composites, as verified by SERS testing and UV-Vis-NIR absorption spectra. It was found that the LSPR absorption wavelength can be easily tuned from 950 to 735 nm by changing the sputtering power of MoO3. The relationship between carrier density and SERS intensity change caused by electromagnetic enhancement was investigated using Hall effect measurements. These findings provide insights into tunable LSPR and the contribution of electromagnetic effects to SERS.

Summary: The purpose of this study is to investigate the charge transfer process and SERS enhancement mechanism in the Ag/MBA/PAN system with varying thicknesses of PAN. The results show that increasing the PAN thickness leads to higher frequency and intensity of the characteristic MBA band, as well as increased intensity of the b2 mode. The degree of CT also increases with increasing PAN thickness, due to the excited SPR from Ag. The electromagnetic enhancement mechanism at the PAN/Ag interface generates hot electrons and facilitates electron transfer in the CT process.

Summary: Surface-enhanced Raman scattering is a powerful method to detect molecules at very low concentrations. In this study, gold nanoparticle dimers were self-assembled using DNA origami nanotriangles, with Cy5 and TAMRA as SERS probes. The results showed that the EFs for the dimeric assemblies follow a log-normal distribution and that plasmonic resonance is the main source of the observed signal.

Summary: In this study, we for the first time observed and considered the plasmonic coupling between noble-metal and semiconductor nanostructures in metal/semiconductor heterostructures, using a W18O49/Ag heterostructure composed of Ag nanoparticles and W18O49 nanowires. The heterogeneous structure exhibited a broad and strong surface plasmon resonance (SPR) absorption in the visible wavelength range. Surface-enhanced Raman scattering (SERS) was used to investigate the interactions between metal SPR, semiconductor SPR, and the heterostructure's charge transfer process, revealing that the coupled SPR enhanced the heterostructure's internal charge transfer and SERS signals. A new coupled-plasmon-induced charge transfer mechanism was proposed to explain the improved charge transfer efficiency. This work provides insights for further studies on plasmonic effects and interfacial charge transfer in metal/semiconductor heterostructures.

Summary: Engineering hotspots in surface-enhanced Raman spectroscopy (SERS) by precisely controlling the assembly of plasmonic nanostructures can enhance the potential of SERS for single molecule detection. Plasmonic dimer nanoantennas with tunable gaps showed significant enhancements for single dye molecules, and were able to detect a single thrombin protein molecule in a 10 nm wide nanogap. These engineered nanoantennas have the potential to serve as a broadband SERS enhancer for specific detection of biological molecules with single-molecule sensitivity.

Summary: Plasmon-enhanced stimulated Raman scattering (PESRS) microscopy has been developed to achieve single-molecule detection limit. The dispersive-like vibrational line shapes observed in PESRS can be explained by the interference between the local enhanced electromagnetic field induced by the plasmonic nanostructure and the molecular dipole-induced field. The PESRL and PESRG signals exhibit similar signal magnitudes but show reversed dispersive profiles under the same laser wavelength.

Summary: The height dependence of Raman light scattering on organic molecules deposited onto thick one-dimensional metal-dielectric gratings is investigated. Oscillations of the Raman light scattering intensity as a function of the height of the metastructure's strips are observed, and it is demonstrated that these oscillations are associated with a type of Fabry-Perot effect. It is shown that the intensity of surface-enhanced Raman scattering can be further increased by local field enhancement due to coupling of the surface plasmon polaritons on the top and bottom metal parts of the gratings.

Summary: Phosphorylated adenosine derivatives play important roles in the energetic balance of the cell, biosynthesis of cell components, and regulation of protein activity. Surface-enhanced Raman spectroscopy (SERS) is an optical method that can provide a unique spectrum of a substance at low concentrations. By using nucleic acid aptamers and Raman-active dyes, the specificity and limit of detection of SERS-based sensors can be significantly increased. In this study, a biosensor based on the AMP-dependent interaction between a DNA aptamer and a novel Raman-active dye was described, showing a low limit of detection and a wide dynamic range.

Summary: This study investigates the dependence of the intensities of Stokes and anti-Stokes scattering components on pump power in plasmon-dielectric structures optimized for giant enhancement of Raman scattering (SERS) in the infrared spectral range. The results show that the intensity of the anti-Stokes scattering increases superlinearly with pump power, with a faster increase above a certain threshold power. In contrast, the Stokes scattering intensity is a linear function at low pump powers and a sublinear function at high pump powers. The threshold power is found to depend on the concentration of organic molecules and the SERS enhancement factor. The observed behavior suggests the importance of stimulated light scattering mechanism in SERS structures. Analysis of the spectral positions of scattering lines indicates that molecules are excited to high vibrational energy levels under above-threshold laser excitation, leading to the redshift of anti-Stokes scattering lines.

Summary: In light of recurring epidemics and pandemics, rapid and reliable virus identification techniques are needed. Polymerase chain reaction with reverse transcription is a reliable and sensitive, though not rapid, tool. The antibody-based strip is a rapid, though not reliable, and sensitive tool. Alternative tools are being developed to meet all the customer's needs, such as surface-enhanced Raman spectroscopy (SERS) which allows single molecule detection in minutes. A multiplex lithographic SERS aptasensor was developed to detect several respiratory viruses in one pot within 17 min by using labeled aptamers anchored onto metal surfaces.
