Summary: Colloidal crystal engineering with DNA has advanced to tuning crystal habits and size by separating nucleation and growth in a given crystallization process. By intentionally introducing mismatches in complementary particles, weaker binding growth particles can participate in heterogeneous growth on stronger binding seed particles, effectively eliminating secondary nucleation pathways. This approach improves crystal uniformity and enables the synthesis of core-shell colloidal crystals.

Summary: The use of bovine serum albumin (BSA) as a protectant for silica nanoparticles (SNPs) in freeze-drying process results in solid structures with excellent redispersibility and minimal signs of aggregation even after longer storage times. The formation of a saturated BSA corona around the nanoparticles before lyophilization process prevents massive system aggregation and suppresses non-specific interactions between the nanoparticles and biological systems, indicating potential for BSA as an additive for nanoparticle freeze-drying in generating solid and redispersible nanoformulations with improved biocompatibility.

Summary: The colloidal stability and controlled assembly of functional colloidal nanoparticles are two major aspects. This study reveals the relationship between the ligand shell structures, interparticle interactions, and dynamical behaviors of small-sized nanoparticles capped with hydrocarbon chain ligands, and discovers a transformation of interparticle interactions from anisotropic attractions to isotropic repulsions caused by the change in ligand shell structures.

Summary: This paper provides a theoretical analysis of the elastic moduli of colloidal rods immersed in a thermotropic liquid-crystalline solvent by considering various interactions between the rods and the solvent as well as between the rods themselves. The study shows that the presence of colloidal rods significantly increases the splay elasticity in uniaxial systems, and only a small subset of elastic constants play a relevant role in describing the nematoelastic properties of orthorhombic hybrid liquid crystals. The complexity and possibilities related to identifying the elastic moduli in experiments are briefly discussed.

Summary: In this study, we investigate the structural correlations in strongly asymmetric mixtures of binary charged colloids. We find that the amplitude of the big-small correlation peak is smaller than that of the big-big and small-small correlation peaks. Furthermore, we discover that an additional shifted Gaussian attractive potential between the small macroions is needed to accurately reproduce their correct pair correlations.

Summary: Self-organized supramolecular assemblies are commonly found in nature and technology, and their reversible non-covalent bonding allows for dynamic functions such as stimuli-responsive switching and self-healing. However, the specific dynamics of these assemblies remain unclear due to the diverse molecular motions generated by multiple intermolecular interactions.

Summary: Time-resolved second harmonic generation spectroscopy was used to investigate the changes in adsorption and transport properties of MGITC dye to DOPC liposomes induced by acetaminophen. The study found that acetaminophen increased the adsorption of MGITC to the liposome interface and decreased the transport rate. This research provides a detailed foundation for developing potential liposome-based drug-delivery systems.

Summary: In this study, an ionic covalent organic framework (iCOF) surface grafting monolithic sorbent was prepared for in-tube solid-phase microextraction (SPME) of aristolochic acids (AAs) in various samples. The density of quaternary ammonium ions in the iCOF was modulated for enhanced adsorption of AAs. The iCOF surface grafting monolithic sorbent was confirmed by different means. Several operating conditions were optimized to develop the online in-tube SPME-HPLC method, which showed good linearity, low limits of detection, and high recoveries for AAs in serum samples. This study presents a feasible approach for the application of COF-based monolithic sorbents in sample preparation.

Summary: A chitosan-alginate sponge with multiple cross-linking networks was developed for adsorption and enrichment of anionic dyes from food samples. The sponge showed better three-dimensional network structure, mechanical behavior, and stability compared to pure chitosan and alginate sponges. The adsorption performance and selectivity of the sponge were systematically studied, and it maintained high adsorption capacity and selectivity for anionic dyes. The sponge also showed satisfactory reusability and was successfully combined with high-performance liquid chromatography for the enrichment and detection of anionic dyes in candy and cocktail samples.
