Summary: Bimetallic AuRh_Au nanorod dimers with a thin lossy Rh segment in the gap region were synthesized using OWL. The E-field enhancement at the Rh segment and the coupling between the Au NR antennas were investigated using EELS, electromagnetic simulations, and SERS. Simple design rules for maximizing the E-field at a given wavelength within and on the Rh were provided. These bimetallic NR dimers are versatile platforms for studying plasmonic coupling in heterostructures and have potential applications in plasmonic catalysis.

Summary: This study aimed to enhance surface plasmon resonance by combining Ag nanoparticles and an asymmetric crater structure. The results showed that the Raman intensity inside the crater with Ag nanoparticles and nanowires was 22 times higher compared to a flat area without nanoparticles. However, an increase in the amount of nanowires led to a decrease in Raman intensity.

Summary: A facile and green synthesis strategy was used to prepare a uniform three-dimensional (3D) nanostructure as surface-enhanced Raman scattering (SERS) sensors by decorating Ag nanoparticles (AgNPs) on TiO2 nanorod arrays. The AgNPs were distributed uniformly on the surface of TiO2 nanorods, as confirmed by XPS, SEM, and TEM analyses. The 3D hybrid substrate exhibited sensitive SERS signals and excellent spatial uniformity. The results also demonstrated the promising potential of the two-step synthesis strategy for preparing 3D hybrid nanostructure substrates for SERS.

Summary: Surface-enhanced Raman scattering is a powerful method to detect molecules at very low concentrations. In this study, gold nanoparticle dimers were self-assembled using DNA origami nanotriangles, with Cy5 and TAMRA as SERS probes. The results showed that the EFs for the dimeric assemblies follow a log-normal distribution and that plasmonic resonance is the main source of the observed signal.

Summary: In this study, the high-pressure structural and electronic transitions of SbI3 under different hydrostatic environments were investigated using synchrotron X-ray diffraction, Raman spectroscopy, electrical conductivity, and first-principles theoretical calculations. It was found that SbI3 exhibited an electronic transition from semiconductor to metal at 32.3 GPa under non-hydrostatic conditions. A pressure hysteresis of about 5.0 GPa was observed for the metallization of SbI3 under hydrostatic conditions, possibly due to the faint deviatoric stress. Moreover, the phase transition of SbI3 was found to be irreversible under different hydrostatic environments. This study provides insights into the correlations between crystalline and electronic structures and may facilitate the application of quasimolecular layered crystals in optoelectronic devices.

Summary: In this study, researchers found that the expression levels of galectin-3 were higher in the peripheral blood mononuclear cells of SLE patients compared with normal individuals and positively correlated with lupus nephritis and SLE disease activity index. They also observed NETosis in normal individuals, SLE patients, and galectin-3 knockout mice. Furthermore, galectin-3 was found to be associated with NETs and immune complex deposition in SLE patients. These findings provide clinical relevance of galectin-3 in SLE and offer insights into the underlying mechanisms of galectin-3-mediated NETosis for developing novel therapeutic strategies targeting galectin-3 for SLE.

Summary: Molnupiravir is an oral ribonucleoside prodrug used for the treatment of COVID-19. It can cause adverse effects such as headache, diarrhea, and nausea, possibly due to its impact on sodium channel function. In this study, the researchers investigated the effect of Molnupiravir on voltage-gated Na+ current in pituitary GH3 cells and found that it had specific effects on both transient and late Na+ currents, as well as altering the inactivation time constant of the slow component of Na+ current. The IC50 values for Molnupiravir in inhibiting transient and late Na+ currents were 26.1 and 6.3 μM, respectively. The study suggests that the alteration of Na+ currents by Molnupiravir may have important physiological implications and contribute to its pharmacological activity or adverse events.
