Summary: This work demonstrates the formation of hollow nanoparticle layers using metal island films as templates, where the morphology and plasmonic properties of the islands gradually change with the increase of titration solution concentration. The hollow island films obtained with large titration concentration show a significant enhancement in refractive index sensitivity factor and figure of merit compared to untreated samples, showing promise for cost-effective fabrication of plasmonic sensors.

Summary: This study investigates the influence of media on the interaction between ultra-fine plasmonic nanoparticles and radiation. It demonstrates the important role of the surface layer of the nanoparticles and the highly inhomogeneous distribution of the electric field. The results show that an increase in the refractive index of the ambient medium leads to the extension of the surface layer and an enhanced red shift of the plasmon resonance band.

Summary: A dual channel sensor based on silver nanostructures was proposed for simultaneous detection of magnetic field and temperature. By optimizing the structural parameters and channel size, the sensitivity of both temperature and magnetic field was enhanced. Additionally, the detection of a single parameter was achieved by placing materials in both channels.

Summary: In this paper, mesoporous metal fluoride films with precisely tunable refractive indices are prepared using a precursor-derived one-step assembly approach. The films exhibit a wide range of refractive indices (from 1.37 to 1.16 at 633 nm) due to the mesoporous structures formed through the interaction of Mg(CF3OO)(2) and La(CF3OO)(3) ions. Additionally, the authors create a gradient refractive index coating using multiple MgF2(1-x)-LaF3(x) layers, achieving high transmittance and antireflection properties.

Summary: In this paper, opto-plasmonic sensors are designed by arranging gold nanospheres and using DNA-gold nanoparticle (GNP) core-shells and DNA rods as junctions. The structures show high sensitivity in distinguishing materials based on refractive indices, and can be utilized for spectroscopy and optical imaging on a real scale. Different topologies of the proposed structures are analyzed, with the core-shell heptamer structure showing the best sensitivity and DNA rods as junctions between GNPs showing the best figure of merit value.

Summary: In this paper, a D-shaped optical fiber plasmonic sensor using planar and grating structures of silver and gold metals is simulated. Performance of the sensor is evaluated based on the transmittance curve and electric field distribution of a surface plasmon wave. The results show that gold has a wider bandwidth than silver, but it decreases the detection accuracy, while gold has a higher shift in resonance wavelength, which improves sensor performance and enhances sensitivity.

Summary: We report the dielectric sensitivity of fluorine and tin codoped indium oxide nanocubes and its dependence on their sharp faceting and tin-dopant concentration. The plasmon mode associated with the nanocube corners is the most sensitive and increasing dopant concentration enhances dielectric sensitivity. Simulation results suggest that the plasmon modes associated with the edges and faces of the nanocubes are less sensitive than expected due to the presence of band bending and a resulting surface depletion layer.

Summary: This study reports the dielectric sensitivity of fluorine and tin codoped indium oxide nanocubes and its dependence on their sharp faceting which gives rise to multiple plasmonic modes and on their tin-dopant concentration. It is found that the plasmon mode associated with the nanocube corners is the most sensitive and that raising dopant concentration increases dielectric sensitivity.

Summary: Flat optics nanogratings supported on thin free-standing membranes combine narrowband waveguided modes and Rayleigh anomalies for sensitive and tunable biosensing. Sharp waveguided modes and lattice resonances were achieved on high-refractive index Si3N4 membranes using lithographic nanogratings based on plasmonic nanostripes. These optical modes were fine-tuned over a broadband Visible and Near-Infrared spectrum, supporting strong near-field amplification and enabling versatile biosensing applications.

Summary: This paper presents a quintuple Fano resonance (FR) achieved through a metal-insulator-metal (MIM) waveguide system. The composite structure consists of a connected-ring resonator (CRR) and a defective-ring resonator (DRR) coupled to a MIM bus waveguide. The study shows that the Fano line shapes can be individually tuned by the geometrical parameters.

Summary: The paper proposes an extension of Babinet's principle for plasmonic metasurfaces by redefining the concept of complementary screens and finding impedance relations, leading to a simple relation between the transmission matrices of two complementary plasmonic metasurfaces. The theory is valid under the assumptions of the electroquasistatic approximation and plane waves in the far field, with potential applications in the design of optical plasmonic metasurfaces, nanocircuits, and nanoantennas.

Summary: This review discusses recent studies on coupled plasmonic systems for controlling plasmon dynamics and molecular detection using spectral modulations. The plasmon dephasing time can be controlled by weak and strong coupling regimes between plasmonic nanostructures or localized surface plasmon resonances (LSPRs) and other optical modes, such as microcavities. Modal coupling extends the plasmon dephasing time, enhancing near-field enhancement at specific wavelengths for improved molecular detection.
