Summary: This article compares the applications of traditional gold and silver-based SERS substrates and less conventional substrates on sensing, biosensing, and clinical analysis. The results show that Si and Al-based substrates, when combined with gold and silver nanostructures, can produce comparable results to conventional substrates with lower cost and better stability. They can be considered as alternatives to gold and silver-based substrates.

Summary: Metasurfaces have the ability to confine electromagnetic fields on large surfaces and zones, making them suitable for applications in biochemical sensing, photocatalysis, etc. They enhance the effects of SERS and SEIRA sensing by the presence of hotspots and confined optical modes within their structures, as well as by supporting resonances at frequencies of the excitation and emission processes. Additionally, Metasurfaces enhance the absorption capacity of solar light and generate more catalytic active sites for faster surface reactions.

Summary: Homogeneous surface-enhanced Raman scattering (SERS) sensors have great potential in environmental analysis by allowing in situ analysis and continuous monitoring of pollutants without the need for laboratory analysis of collected samples. These sensors utilize functional DNA strands on the surface of SERS-active particles and can be adapted to detect small molecules through the use of aptamer sequences. However, the design rules for aptamer-based SERS sensors have not been established, limiting their full adaptability. This study aims to define a design protocol for aptamer-based homogeneous SERS sensors and demonstrates its application for ATP and estradiol detection.

Summary: The first application of aluminum foil as a low-cost/high-availability substrate for sandwich immunoassay using surface-enhanced Raman spectroscopy (SERS) is reported. It showed comparable limits of detection (LODs) for tuberculosis biomarker MPT64 with traditional sandwich ELISA using gold film, but with a large cost/availability advantage. Furthermore, it exhibited better selectivity and lower nonspecific response compared to gold film in human immunoglobulin (hIgG) assays.

Summary: This theoretical study demonstrates that a giant electromagnetic field can be generated in a supernarrow nanoslit formed by a silver cylinder and a flat mirror surface, resulting in resonant amplification of the field due to the excitation of gap plasmons. The amplification of the electric field increases with decreasing distance between the surfaces and reaches saturation, leading to record high field intensity exceeding the incident wave intensity by ten orders of magnitude. The discovered gap plasmon modes will enhance the sensitivity of detecting small concentrations of molecules, down to single molecules, using giant Raman scattering of light and plasmon-enhanced IR spectroscopy.

Summary: Mesoscopic Photonic Crystals (MPhCs) are composed of alternating natural or artificial materials with compensating spatial dispersion, allowing self-collimation of light. A new design method is proposed for conceiving MPhCs that allow MSC under oblique incidence, avoiding in-plane scattering and ensuring propagation via purely guided modes. This simple yet powerful method can pave the way for the design of advanced MSC-based photonic interconnects and circuits immune to crosstalk and out-of-plane losses.

Summary: This study numerically demonstrates that surface lattice resonances (SLR) can be excited in periodic localized surface plasmon (LSP) waveguides integrated on a dielectric waveguide through in-phase evanescent coupling, even when the structure lacks symmetry. The coupling between wideband LSP resonances and narrowband SLR produces a Fano-like resonance, which exhibits sharp spectral features in the nanometer scale, suggesting potential applications in integrated optics and sensing.

Summary: In this study, we investigated chemical sensing using surface-enhanced Raman scattering with gold nanocolumn templates. The glancing angle deposition with magnetron sputtering technique was chosen for its low-cost production and ease of implementation. The fabricated gold nanocolumnar structures allowed for the production of a high density of strongly confined electric field spots. The vertical and tilted nanocolumnar templates showed promising results for the detection and adsorption of thiophenol molecules.

Summary: This study investigates the Fermi level shifts of gold nanospheres on zinc oxide (ZnO) film upon UV irradiation. The shifts are obtained by recording the extinction spectra of gold nanospheres and are attributed to the additional electrons stored in the nanospheres from ZnO film. The blueshift of plasmon resonance of the Au nanospheres indicates the transfer of electrons from ZnO film to Au nanospheres upon UV irradiation. The Fermi level shifts vary with UV irradiation time and can be estimated by a model based on the electronic structure of a semiconductor.

Summary: This study presents generic, analytical equations for the localized plasmons in a narrow gap between a metal/dielectric cylinder and a metal surface. The electric field distribution in the nanogap is obtained using the quasi-static approximation. The maximum electric field is achieved when the incident light is in resonance with the plasmon mode in the gap, and can be significantly enhanced. The analytical model results are in good agreement with a known theoretical model and experimental results of surface-enhanced Raman scattering (SERS). The narrow gap resonator appears to be a powerful and flexible tool for various spectroscopies such as SERS and infrared absorption.
