Summary: After the Fundao iron ore mining dam rupture in November 2015, yellow/ocher emulsions were observed on the continental shelf adjacent to the Doce River, composed of nanoparticles of iron oxyhydroxide. Analysis revealed the presence of micelles made up of these nanoparticles enveloped by organic polymers, which may act as a self-assembly template seed after losing water. This study highlighted the distinct behavior of tailings material compared to clay minerals previously found in suspended particulate material before the dam rupture.

Summary: In this study, the controllable self-assembly of DNA-linked gold nanoparticles (AuNPs) for in vivo biomedical applications was achieved by using programmable DNA tetrahedral structures. Three different sizes of AuNPs (20nm, 10nm, and 5nm) were organized and positioned using this method. The density and arrangement of the satellite AuNPs around the core AuNPs were controlled by tuning the size and amount of DNA tetrahedron functionalized on the core AuNPs, resulting in strong electromagnetic field enhancement. With the conjugation of Raman molecules, strong surface-enhanced Raman scattering photoacoustic imaging signals were generated, allowing for the imaging of microRNA-21 and tumor tissues in vivo. This study provides an efficient strategy for building precision plasmonic superstructures in plasmonic-based bioanalysis and imaging.

Summary: The introduction of a hollow plasmonic structure led to enhanced surface plasmon-coupled emission (SPCE), resulting in significant fluorescence signal enhancements. This was primarily attributed to the unique hot-spot plasmonic structure between GNS and gold substrate, the intense electromagnetic field of GNSs, and the strong coupling interactions between fluorescence and surface plasmons.

Summary: Monoclonal antibodies with optimized Fc domains show superior potency in preventing and treating COVID-19 in animal disease models, reducing the dose required for protection against SARS-CoV-2 challenge and for treating pre-infected animals. Selective engagement of activating Fc receptors results in improved efficacy, highlighting the importance of Fc receptor pathways in driving antibody-mediated antiviral immunity. These findings have implications for the development of Fc-engineered monoclonal antibodies with optimal Fc-effector function against COVID-19.

Summary: Stimuli-responsive self-assembly of plasmonic magnetic dumbbell Janus nanoparticles (Au-Fe3O4) was demonstrated using the host-guest interaction of cyclodextrin and arylazopyrazole. Efficient ligand exchange procedures allowed the introduction of functional ligands to the gold or magnetite core of the dumbbell, leading to distinct nanoparticle superstructures in aqueous solutions. These superstructures could be modulated with light, showing reversible formation and fragmentation.

Summary: The acquisition of strong chiroptical activity has revolutionized the field of plasmonics, enabling new light-matter interactions. Self-assembly of achiral nanoparticles into optically active materials simplifies engineering of chiral geometries and allows for control of structure-optical activity relationships in nanostructures. Chiral structures like helical assemblies and patterned substrates are reviewed as platforms for chiral sensing, with future potential for incorporating semiconductor emitters into plasmonic systems to generate circularly polarized photoluminescence.

Summary: This study presents an efficient and simple strategy to grow precision helical hybrid microwires by systematically assembling cationic gold nanorods along chiral tobacco mosaic virus particles via electrostatic attraction. The resulting composite superstructures exhibit a strong circular dichroism response at the plasmon wavelength of the gold nanorods. This generic methodology using inexpensive templates encourages the exploration of a wider range of nanoscale templates for creating hybrid mesostructures with emerging optoelectronic properties.

Summary: This study reports a straightforward method for synthesizing red, green, blue and violet emitting AuNCs in pure ethylene glycol with the addition of aniline or indole. By using advanced microscopy, mass spectrometry, and spectroscopy techniques, different sizes of AuNCs were identified and found to emit pure white, blue, green, and violet luminescence. The AuNCs were made water soluble and stable while preserving their photo-physical characteristics by capping them with a thiopegylated ligand shell bearing a carboxylate, amine or biotin. These findings have potential applications in biolabeling, hyperspectral sensing, and display technology.

Summary: Our study shows that poly(vinyl pyrrolidone) (PVP), commonly used as a surface passivation agent, actually promotes surface oxidation of copper nanowires (Cu NWs), leading to decreased stability and performance of transparent conducting electrodes (TCEs). Instead, we propose using polyimide (CPI) as a protective layer, which significantly improves the stability of Cu NW TCEs. Conductivity measurement over 90 days shows no major degradation, while the reference TCE degrades completely after approximately 15 days. Furthermore, we demonstrate the successful application of Cu NW TCEs in thin-film transistors (TFTs) and organic solar cells, with good operational stability.

Summary: Applying voltage can transform a nanoscale dielectric gap between two metal electrodes from insulating to highly conducting, which is widely used in emulating synapses in neuromorphic neural networks. Volatile resistive switching can release electromagnetic radiation in the visible spectral region, and the emitted spectrum is characterized by photon energies exceeding the maximum kinetic energy of electrons provided by the switching voltage. Photonic memristors with different memristive gaps can sustain different emission mechanisms and bring alternative ways to generate light on chip and optical interconnects.
