Summary: Single Molecule Orientation and Localization Microscopy (SMOLM) is gaining popularity in the field of localization microscopy due to its ability to monitor orientation as well as spatial information. This study quantifies the bias introduced by incident polarization in SMOLM readout using analytical derivations, and demonstrates this effect experimentally on single molecules attached to a surface with wobbling.

Summary: This study investigates the potential of an Si-SiO2-ZnO-Au nanoparticles (NPs) structure based plasmonic multilayer FET design for sensing applications. The effects of design parameters such as the diameter of Au NPs, obliqueness of light incidence, and spacing between Au NPs on the sensor's sensitivity are studied. The incorporation of 3-mercapto propionic acid (3-MPA) with Au NPs is also examined for increased sensitivity. The results show that the size of NPs and angle of light incidence have a coupled effect on the sensitivity.

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 article focuses on determining the 3D orientation of single gold nano-bipyramids (AuBPs) and deducing orientation through polarization resolved dark-field scattering. The study presents a specific experiment for selecting, analyzing, and resolving the scattering angles of individual nanoparticles. The accuracy of polarimetric measurements is evaluated through a comparison with a complete measurement of the degree of polarization (DOP) as a function of the collected numerical aperture.

Summary: Combining metal nanoparticles with localized surface plasmon resonance (LSPR) with metal-organic framework (MOF)-based photocatalysts is an effective way to enhance the separation of electron-hole pairs. In this study, Au@NH2-UiO-66/CdS composites were synthesized by encapsulating Au nanoparticles with LSPR into NH2-UiO-66 nanocages and growing CdS nanoparticles on the surface. The composites exhibited higher photocatalytic activity in hydrogen evolution reaction compared to NH2-UiO-66/CdS and CdS alone under visible-light irradiation. The study also revealed the important role of MOF in transferring electrons and receiving hot electrons generated from plasmonic Au in Au@MOF/CdS composites to enhance the photocatalytic performance.

Summary: The study reveals a novel global geometric structure of transmission eigenfunctions associated with the Helmholtz system, demonstrating the localization of eigenfunctions under certain conditions. A comprehensive theoretical justification is provided for the radial geometry, while extensive numerical experiments are conducted for the nonradial case. This discovery offers a new perspective on wave localization and has practical applications in super-resolution imaging and pseudo surface plasmon resonant modes.

Summary: In this study, the signal strength of a localized surface plasmon resonance (LSPR) biosensor based on optical fiber end-face was enhanced by designing an AuNP multimer structure. The biosensor showed higher sensitivity and lower limit of detection compared to biosensors with AuNPs alone. This strategy can be applied in the research and development of various biosensors.

Summary: The remote excitation and remote-controlling of the localized surface plasmon resonance (LSPR) in a heterotype and hollow gold nanosheet (HGNS) is investigated using FDTD simulations. The LSPR wavelength and peak intensity in the HGNS depend on factors such as the polarization of the incident light and the symmetry of the heterotype structure. By optimizing the parameters, significant polar plots of the polarization-dependent LSPR peak intensity with various patterns are obtained, showing the potential applications in remote-controllable surface-enhanced Raman scattering (SERS), optical interconnects, and multi-channel waveguide switches.

Summary: Metal nanovoid (NV) and metal on metal nano-hemisphere (MoNH) structures are introduced to tune the localized surface plasmon resonance (LSPR) for wider wavelength ranges. These structures enable flexible tuning of the LSPR in the UV and NIR wavelength regions, respectively, and are fabricated via thermal annealing of deposited metal thin films. Both experimentally and numerically verified, these structures provide effective means of adjusting LSPR.

Summary: The multilayered Au@MnOx@SiO2 nanoparticle was developed as a robust pH-sensitive plasmonic nanosensor for real-time monitoring of dynamic acidification features during phagosome maturation process in macrophages. The color changes of nanoprobes indicated a slow-to-fast acidification translation over time, which was related to V-ATPase activation. This nanosensor shows promise for studying phagosome dysfunctions and related disease pathogenesis.

Summary: The study revealed that during dynamin accumulation peak, vesicles carrying cargos undergo sudden and rapid super twists, followed by detachment from the cell membrane. This indicates that dynamin-mediated vesicle scission is mainly driven by a large torque generated by the coordinated actions of multiple dynamins.
