Summary: Al-Cu bimetallic nanoparticles thin film was fabricated by Nd:YAG fiber pulsed-laser irradiation of Al/Cu bilayers, and the effects on morphology, structure, composition, and optical properties were studied. Tunability of both localized surface plasmon resonance wavelength and intensity was achieved by adjusting the pulse shot or relative thickness of the bilayers. SEM analysis revealed that the obtained particles had a mean diameter of 36-80 nm, dependent on the Cu proportion. Surface-enhanced Raman spectroscopy measurement and FDTD simulation were used to verify the LSPR properties before and after laser irradiation.

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: 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: Due to the increasing importance of nanosensors in the early diagnosis of diseases, researchers propose a structure consisting of plasmonic nanoshells with spherical and ellipsoidal geometry to calculate the refractive index changes. The sensitivity of the nanosensor is computed and factors such as geometry, material, dimensions, thickness, and surrounding environment are studied. The results show that ellipsoidal nanoshells are more sensitive to RI changes, and bimetallic nanoshells can exponentially increase the sensitivity of the nanosensor.

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 spectral difference between formononetin (F) and ononin (FG), two isoflavones, is explained through a study of their fluorescence molecular structure. The fluorescence enhancement of FG in hot alkaline conditions is reported for the first time. F exhibits fluorescence only at pH >4.8 due to deprotonation of 7-OH, while the anionic form of F produces strong and stable fluorescence between pH 9.3 and 12.0. The fluorescence quantum yields of F and FG are measured to be 0.042 and 0.020, respectively. The differences in fluorescence characteristics between F and FG allow for the identification and quantitative analysis of components in Chinese herbal medicine.

Summary: In this work, a portable analytical system based on point discharge chemical vapor generation atomic emission spectrometry (PD-CVG-AES) coupling with gold filament enrichment was designed. The highly sensitive analysis of Hg2+ indirectly realized the detection of ascorbic acid (AA). The measurement is based on the fact that Ag+ can decrease the concentration of Hg2+ by forming Ag-Hg amalgam in the presence of the reductant SnCl2, while AA can pre-reduce Ag+ to Ag0, leading to the generation of silver nanoparticles (Ag NPs). The developed novel analytical strategy broadens the application of microplasma-based AES and offers a higher level of sensitivity compared to current AA detection techniques.
