Summary: New homochiral (AgRhIII)-Rh-I nanoclusters, Delta(6)/?(6)-[Ag11S{Rh(apt)(3)}(6)](9+) and Delta(6)/?(6)-[Ag13S{Rh(apt)(3)}(6)](11+) were successfully synthesized using different sulfide sources in water. The cluster cores of [1](9+) and [2](11+), protected by fac-[Rh(apt)(3)] metalloligands, consist of Ag11S and Ag13S, respectively. Photoluminescence switch from nonemissive [1](9+) to emissive [2](11+) was achieved by converting [1](9+) to [2](11+) through the reaction with Ag+.

Summary: Atomically precise silver nanoclusters are a hot research area with a lack of understanding in the synthesis mechanisms. A novel two-dimensional 14-nucleus silver poly-cluster has been designed and synthesized with high stability and excellent performance in energy density, cycling stability, and capacity, making it a potential green energy source.

Summary: With the use of anion template-driven self-assembly, we have achieved precise control over the shape and size of silver nanoclusters, reporting the atomically precise structures of Ag37 and Ag46. The results reveal that Cl- ions serve as both local and global templates in Ag37, while CrO42- ions function as local templates with Cl- ions as global templates in Ag46. By utilizing the deep cavity of thiacalix[4]arene with an extended phenyl group, Ag46 has been successfully used as a host material for dye adsorption depending on the charge and size of organic dyes. The study fills the knowledge gap in understanding the directing role of heteroanions in dictating the shape and size of nanoclusters at the atomic level.

Summary: A series of heterometallic tetrahedral cluster complexes were synthesized by reacting ReI3 and MO3 with selenium and KCN at elevated temperatures. Crystal structures, electrochemical properties, and magnetic properties of the crystalline samples were studied in detail. Results showed that the new cluster anions exhibit regular changes in geometric characteristics and redox potentials depending on the composition of the cluster core.

Summary: This study expands upon previous work on amphiphilic-grafted nanoparticles and investigates their oil encapsulation properties through UV and DSC analysis. The results suggest that these nanoparticles can encapsulate a significant amount of crude oil and do not have a critical micelle concentration.

Summary: In this study, a generally applicable silica encapsulation method using TMPS was developed for non-hydrophilic optical nanoparticles, such as quantum dots and gold nanoparticles, to enhance their biocompatibility and stability. The fabricated silica-encapsulated nanoparticles showed optical properties without significant changes in the quantum yield or Raman signal intensity.

Summary: In this study, the reaction mechanism responsible for the nucleation of {Ag32S3} clusters was investigated using various analytical techniques. Triphenylphosphorus sulfide was found to slow down the nucleation process, and a key precursor was identified, which reacted with Agn(CuCBut)m and traces of water to generate {Ag32S3} clusters. This mechanism provides valuable insights into the synthesis of inorganic magic-size clusters.

Summary: This article describes a modified workflow for the extraction of cell-free DNA from primary samples containing BioCaRGOS, as well as the compatibility of BioCaRGOS with droplet digital PCR analysis for pancreatic cancer biomarkers. Interference with the extraction process and ddPCR analysis was minimized through the removal of methanol and invert filtration. These modifications allow for the stabilization and extraction of nucleic acid biomarkers using BioCaRGOS while retaining the capability of quantification based on ddPCR.

Summary: This study developed a novel and effective strategy to monitor the real-time release of hydrophobic cargo curcumin using a lipid-curcumin-loaded silica colloidal crystal film controlled by lipase. The degradation of a digestible lipid complex triggered by lipase resulted in the real-time release of curcumin, which was tracked by changes in optical thickness. The study also found that the addition of soluble dietary fiber delayed the release rate of curcumin.

Summary: This study demonstrates an improved and simple synthetic method for producing stable narrow-sized Gly-CSA-functionalized Au nanoclusters, with the NC size and distribution controlled by reducing agent concentration, resulting in smaller NC core diameters at higher NaBH4 concentrations. The functionalized Au NCs show promising potential for biomedical applications due to their controllable size and facile functionalization.

Summary: We present a simple method to fabricate silica capsules encapsulated with wax using hexadecyltrimethoxysilane-modified silica nanoparticles. These capsules are formed through O/W Pickering emulsion stabilized by the hydrophobic silica nanoparticles at the interface. Molecular dynamics simulations were conducted to analyze the surface-modified silica nanoparticles at the polar-nonpolar solvent interface. The encapsulation efficiency of different waxes as phase change materials was investigated, making these capsules a promising candidate for active micro-fillers in dental cements.
