Summary: The analysis of reactant at different regions of the bioreaction interface is important for studying the impact of interface conditions on bioreactions. In this study, a localized surface plasmon resonance (LSPR) biosensing platform was proposed for monitoring local charge density and detecting corresponding analytes. The researchers synthesized core-shell nanocomposites and modified tin-doped indium oxide (ITO) substrates for optical and electrochemical measurements. By immobilizing glucose oxidase (GOD) on the LSPR chips, the researchers demonstrated monitoring of charge transfer during the bioreaction of glucose catalysis. The charge density of the LSPR chip was detected using optical extinction peak shifts.

Summary: This study demonstrates that localized plasmons in graphene can be generated on a macroscopic scale using couplers based on randomly oriented particle-like nanorods (NRs), eliminating the need for expensive and time-consuming e-beam lithography. Monitoring the excitation of graphene plasmons indirectly by observing the changes in reflection/absorption spectra of methylene blue (MB) or polymethyl methacrylate (PMMA) molecules on the structure reveals enhanced oscillator strengths and Fano scattering related lines asymmetry in reflection spectra due to the hybridization of spectrally broad graphene plasmon and narrow molecular oscillators.

Summary: Surface Plasmon Resonance (SPR) is widely used in biological and chemical sensing, but its application is hindered by non-specific binding and low signal. Hybridization chain reaction (HCR) can amplify signals and provide an enzyme-free alternative for biosensing, by utilizing DNA as an amplifying transducer. Integrating HCR with phase-sensitive SPR (pSPR) can lead to highly informative sensing in biosensing applications.

Summary: This paper presents numerical and experimental results on the effects of spherical gold nanoparticles (AuNPs) size on Localized Surface Plasmon Resonance (LSPR) refractive index (RI) sensitivity, Figure of Merit (FoM), and penetration depth (dp). The study also investigates the influence of AuNP dimer interparticle distance (ds) on these parameters. The results show that a diameter of 60 nm AuNPs provides the best FoM. Furthermore, the interparticle distance between d = 20 nm and 60 nm AuNPs significantly affects the RI sensitivity. The importance of penetration depth information for biosensing using aptamers is discussed in relation to aptamer size.

Summary: In this study, localized surface plasmon lasing at room temperature in the communication band was achieved using metallic nanoholes as plasmonic nanocavity and InP nanowires as gain medium. Optimization of laser performance was demonstrated through coupling between two metallic nanoholes, allowing for manipulation of lasing properties. These plasmonic nanolasers offer lower power consumption, smaller mode volumes, and higher spontaneous emission coupling factors, making them promising for high-density sensing and photonic integrated circuits.

Summary: The performance of photocatalytic reduction of Cr(vi) is improved by tuning the localized surface plasmon resonance (LSPR) of W18O49 nanostructures through morphology control. The blue shift and intensity increase of the corresponding LSPR bands are attributed to morphology changes from nanowires to nanobundles and urchin-like nanospheres, resulting in enhanced photocatalytic activity.
