Summary: This paper reveals the effects of structured light carrying orbital angular momentum (OAM) on surface plasmons, showing anomalous plasmon excitations and couplings under OAM beams. The excitation of single particles is determined by both photon spin angular momentum (SAM) and OAM, and is influenced by particle locations. Fano resonance is observed in a nanorod dimer, with one rod aligned along light propagation direction as the bright mode and the other aligned along global polarization direction as the dark mode.

Summary: The construction of 3D localized surface plasmons (LSPs) in infrared using curved gold nanoshell (AuNS) cylindrical ridges is reported. The strong LSPs are strongly dependent on the perimeter length, the curvature angle, and the thickness of AuNSs. These discoveries explore new approaches to designing plasmonic devices in the infrared using nanoscale structures.

Summary: A scalable and straightforward seed-mediated strategy using oleic acid was developed to produce high-aspect-ratio gold nanorods with high yield. The addition of oleic acid to the growth solution stabilizes the micellar structure of CTAB, facilitating the fabrication of high-aspect-ratio gold nanorods. Additionally, the aspect ratio of the nanorods can be tuned by adjusting the amount of ascorbic acid and the pH of the solution in the presence of oleic acid.

Summary: The study reported changes in the optical properties of Ag nanodomes based on the arrangement and surface coverage of polystyrene (PS) beads used as templates. Increasing the surface coverage of the PS beads led to a transition of reflective colors from yellow to purple in Ag nanodomes, accompanied by a red-shift in resonant wavelengths observed in the reflection spectra. Significant changes were observed in the optical properties when the surface coverage of Ag nanodomes increased from 50% to 60%. The angle dependency of the reflection spectra indicated a switch in the plasmonic mode of Ag nanodomes at these surface coverages.

Summary: This paper explores the design of absorbers using plasmonic metasurfaces in the visible spectrum and presents a comparison between different nanoantennas. The results show that using titanium nitride nanoantennas in plasmonic metasurfaces achieves higher absorption compared to other nanoantennas. This technique provides a promising method for designing preoptimized absorbers for practical applications such as sensing, thermal management, and solar cells.

Summary: A novel stacked dual-band quantum well infrared photodetector with a double-layer gold disk structure was proposed to enhance the photoelectric coupling of two quantum well layers operating at different wavelengths. Numerical simulations demonstrated a significant enhancement in the active regions of the quantum wells at wavelengths of 13.2 μm and 11.0 μm, achieving higher coupling efficiencies compared to traditional optical coupling structures. Structural optimization allowed for red-shifting of the maximum coupling efficiency with increasing disk radius, providing a simpler and more efficient solution for applications requiring infrared detection in complex environments.

Summary: In this study, a mediator release test strategy was designed to photoluminescently sense glutathione using cerium-based nanosheets as a mediator. The strategy also allowed for the successful synthesis of highly chiral AuNCs. A label-free probe for sensitive detection of glutathione was established using this strategy, and it was successfully applied for selective and reliable detection of GSH in human serum samples.

Summary: Electrochemical biosensors have the potential to be cost-effective diagnostic tools for point-of-care testing. However, the sensitivity of directly analyzing complex biological fluids such as plasma has been limited due to biofouling. This study demonstrates a method for creating nanostructured and nanoporous gold electrodes, which greatly increases the surface area and improves detection sensitivity. The surfactant-based electrochemical etch-deposit interplay for nanostructure/nanopore growth (SEEDING) process enhances the sensitivity and antibiofouling capabilities of biosensors, enabling direct analysis of tumor-derived extracellular vesicles in complex biofluids.

Summary: This study obtains the equivalent permittivity distribution of 2D heterostructures using the effective medium theory and analyzes the rotation-induced topological transitions and stack-dependent topological transitions of phonon polaritons. The topological transition points can be predicted by a parameter epsilon x/y, and the phonon polaritons in stacked materials can be precisely designed by controlling the equivalent permittivity. The feasibility of the effective medium theory is verified and the field distributions and dispersions of the 2D heterostructures are compared with the corresponding equivalent structure. The study provides a simpler and clearer criterion for the study of photonic topological transition in anisotropic polaritons and shows great potential in designing multilayer 2D heterostructures.
