Summary: Lanthanide-based upconversion nanoparticles (UCNPs) have attracted scientists' attention for their ability to convert tissue-penetrating near-infrared light into tailored optical illumination inside biological matter. These luminescent UCNPs have been widely used for background-free biorecognition and biosensing. Maximizing NIR light harvesting and upconversion efficiencies while protecting biological tissue is a challenge for laser-assisted photoactivation, and this review provides an overview of recent achievements and challenges in plasmon-modulated upconversion nanoformulations for biosensing applications.

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 thoroughly discusses the effect of Yb3+ on NaErF4-based host-sensitized upconversion (UC) and provides mechanism interpretations. The results show that Yb3+ doping enhances the green UC emission in NaErF4 core nanocrystals, while it weakens the red UC emission in the shell. Furthermore, the UC emission intensity of core-inert shell nanoparticles can be influenced by the shell thickness and lattice mismatch.

Summary: Photodynamic and photothermal therapies are promising candidates for multimodal anticancer therapies, and combining octahedral molybdenum clusters with plasmonic spherical gold nanoparticles can enhance their photophysical properties synergistically. By careful selection of spacing between the cluster and the gold nanoparticle, significant improvements in luminescence and photosensitizing properties of the cluster were achieved compared to similar gold-free particles. The cluster complex also facilitated energy conversion to heat by gold particles, increasing the heating rate under laser irradiation.

Summary: This study introduces a method that combines the plasmon mode of metal nanoantennas with the anapole mode of high refractive index dielectric materials to increase the electric field strength and minimize energy loss. Through numerical simulation and multipole decomposition analysis, the near-field enhancement features and distributions of the electric field are explored using a silicon disk with slots and two Au rings with a coupling mechanism. By generating high-intensity hot spots inside the disk, the electric field can be significantly enhanced, allowing nearby molecules to directly interact with these hot spots, suggesting significant applications in strong photon-exciton coupling and nonlinear photonics.

Summary: To enhance the near-field focusing around nanoscale metal particles, we designed large-sized gold double nanorings with nanoscale gaps between them. These gaps resemble hot halos where single-particle surface-enhanced Raman scattering occurs. The synthesis of these gold nanohalos was achieved using a novel strategy based on hexagonal gold nanoplates as templates. The resulting nanohalos exhibited near-field focusing, confirmed by both experimental measurements and theoretical simulation. The study also revealed a correlation between the distances of intra-nanogaps and particle sizes of gold nanohalos on single-particle surface-enhanced Raman scattering, with high enhancement factors and reproducibility.
