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: 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 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: In this study, the nonlinear optical response of pure and superalkali (Li3O, Na3O, and K3O) doped Si6Li6 clusters has been explored. The doping of superalkalis on the Si6Li6 cluster significantly narrowed the wide energy gap of the pure Si6Li6 cluster and exhibited electride nature. The NLO properties of superalkali doped Si6Li6 electrides, including first and second-order hyperpolarizabilities, were investigated, and a very large quadratic NLO response was observed for the Si6Li6-Li3O complex.
