Summary: By assembling helical plasmonic nanorods with intrinsic chirality, we have created plasmonic metamolecules with both chiral coupling and intrinsic chiroptical responses. These metamolecules offer more dimensions for tailoring chiroptical responses and make it more flexible to design plasmonic nanodevices with custom PCD.

Summary: Significant chiroptical responses can be achieved by chiral coupling of achiral plasmonic nanoparticles or from intrinsic chirality of plasmonic nanoparticles. This study demonstrates the creation of dimeric plasmonic metamolecules with both chiral coupling and intrinsic chiroptical responses. These metamolecules provide more versatility in tailoring chiroptical responses and designing plasmonic nanodevices with custom plasmonic circular dichroism (PCD).

Summary: Supramolecularly assembled high-order supercrystals (SCs) control the properties of semiconductor nanocrystals (NCs) and quantum dots (QDs). Ligand-engineered perovskite NCs (PNCs) form SCs with shorter excitonic lifetimes and higher dielectric constants. Monodentate to bidentate ligand exchange on halide perovskite PNCs generates mechanically stable SCs with close-packed lattices and distinct excitonic properties. Bidentate-ligand-assisted SCs help overcome delayed exciton or carrier recombination in perovskite nanocrystal assemblies or films.

Summary: The study demonstrated that the formation of clusters of gold nanoparticles can enhance photocatalytic activity likely due to the formation of plasmonic hot spots. A 20 ± 12% enhancement in the photocatalytic dye degradation rate was observed by forming clusters of AuNPs through adding L-cysteine, supporting the contribution of plasmonic hot spots to catalytic rate enhancements.

Summary: The researchers present a two-dimensional bimetallic catalyst for efficient hydrogen generation under visible light illumination and solar irradiance by incorporating platinum nanoparticles into a well-defined supercrystal of gold nanoparticles. They observe a correlation between the intensity of the electric field in the hotspots and the boosted catalytic activity of platinum nanoparticles, while identifying a minor role of heat and gold-to-platinum charge transfer in the enhancement.

Summary: This study demonstrates that the strong-coupling regime between quantum emitters and plasmonic resonators can only be achieved under stringent experimental conditions, specifically when the interparticle spacing is less than 2 nm. By actively decreasing the gap between gold nanoparticles to sub-2 nm values through screening electrostatic repulsion at high ionic strengths, the observation of a strong-coupling regime is confirmed through single-nanostructure scattering spectroscopy. Planar facets of polycrystalline gold nanoparticles also play a role in influencing the probability of observing strongly coupled hybrid nanostructures.

Summary: This article demonstrates the stabilizing effect of polyelectrolyte chains on globally neutral aggregates formed through electrostatic complexation. These stabilized complexes, composed of citrate-stabilized gold particles and quater-nized chitosan, are able to retain their nanometric size and stability in saline environment and cell culture media. The plasmonic coupling in these complexes allows for maximized optical absorption.

Summary: An assembly of gold nanoparticles through ligand interaction with short linker molecule 2-picolylamine (PA) is developed to form a strain sensitive network. By combining the nanoparticle network with a lithographically patterned polydimethylsiloxane (PDMS) microstructure, a multistimuli-responsive tactile sensor is created that can effectively transduce mechanical strain to electrical responses. This sensor can identify variable weights, detect finger touch patterns, and has high sensitivity to vibrational movements. In addition, it exhibits strain-dependent plasmonic photodetection properties.

Summary: In this study, plasmonic coupling in gold nanorings with different vertical thickness was investigated using a three-dimensional finite element method. The research found that in very thin gold nanorings, the antisymmetric mode exhibits a redshift at first and then a blueshift as the ratio of inner radius to outer radius increases.

Summary: In this work, a method for fabricating large-area gold nanoparticle superlattices with subnanometer interparticle gaps is demonstrated. The electrical transport measurements reveal significant variations in the nanogap conductance, while in situ optical reflectance measurements show enhanced plasmonic capacitive coupling with decreasing interparticle gap distance. The resulting superlattices also exhibit tunable effective refractive index and extreme field confinement in the high-density subnanometer plasmonic gaps.

Summary: This study investigated the role of the main {314} facet of Bi5O7I, finding that increasing the {008} facet proportion did not effectively improve its activity, while controllable oxygen vacancy concentration could be achieved by constructing a reduction atmosphere. The results showed that the synergistic effect of facet ratio and oxygen vacancies led to an enhancement in charge carrier performance.

Summary: Due to their N-substitution, peptoids are resistant to biological degradation, but the oxidative degradation mediated by reactive oxygen and nitrogen species (ROS/RNS) remains to be fully explored. This study characterizes the degradation of sequence-defined peptoid chains in the presence of chemically generated ROS, and compares it with ROS-susceptible peptides. The results show that peptoids degrade at a similar rate to poly(prolines) under metal catalyzed oxidation conditions, while maintaining resistance to enzymatic degradation.
