Summary: Flupyrimin and nitenpyram, neonicotinoid insecticides, interacted with serum albumins through quenching fluorescence and forming complexes via static process, causing conformational and structure changes. Thermodynamic analysis revealed the interactions were mainly driven by hydrogen bonds and hydrophobic forces, with binding constants indicating nitenpyram had greater stability than flupyrimin in binding with albumins. The acute toxicity bioassay showed low toxicity of both insecticides to zebrafish.

Summary: The development of mitochondria-targeted bovine serum albumins (BSAs) conjugated with fluorescent, lipophilic, and cationic rhodamine 110 molecules enhances the proinflammatory phenotype of macrophages and inhibits their anti-inflammatory phenotype. Porous silicon nanocarriers further boost the immunomodulation of mitochondria-targeted BSAs, accompanied by the secretion of proinflammatory mediators. The mechanism involves the delivery of mitochondria-targeted BSA into macrophages to generate mitochondrial ROS and trigger proinflammatory signaling transduction pathways.

Summary: This study investigated the solvation structures of silver ions in N-butyl-N-methylpyrrolidinium dicyanamide ([BMP][DCA]) using attenuated total reflectance-ultraviolet spectroscopy. The addition of Ag+ caused a red-shift in the absorption band of [DCA]-, opposite to the shift caused by Li+. Multivariate analysis and molecular dynamics simulations revealed that the coordination number of [DCA]- around Ag+ was approximately five.

Summary: In this study, a group of hydrophobic imidazolium-based ILs were immobilized on Ag foams using SCILL method, leading to altered selectivity and CO production rates for the electrochemical reduction of CO2. The change in activity caused by IL is dependent on the length of the N-alkyl substituent, with the rate of CO production optimized at moderate chain length and IL loadings.

Summary: By changing the concentration of PEG-b-PCL and/or changing the solvent using different ILs, the shape transformation of self-assembled PEG-b-PCL nanostructures can be effectively induced to generate nonspherical polymersomes, such as worm-like aggregates, stomatocytes, nanotubes, large hexagonal and tubular-shaped polymersomes, providing a promising platform for the design of biodegradable soft dynamic systems. These systems can be used in the micro/nano motor field for cancer-targeted delivery, diagnosis and imaging-guided therapy, and controlled release of therapeutic drugs for the treatment of various diseases.

Summary: This study investigates the interactions between two gemini surfactants and a biodegradable ionic liquid, and explores their potential applications in pollutant remediation. The results show that the presence of the ionic liquid decreases the critical micelle concentration and facilitates the aggregation process of the surfactants. It is also found that the structure of the gemini system undergoes a transition in the presence of a potential chiral pollutant, which can be used as an analytical signal for selective detection and binding of pollutants.

Summary: Contamination in global water has become a serious issue, and scientists are working tirelessly to find solutions to recycle and reuse wastewater by removing pollutants. Ionic liquids (ILs) and deep eutectic solvents (DESs) have shown unique capabilities in purifying water resources and are being considered as options for removing contaminants. This article highlights the successful application of green ILs and DESs in addressing various types of contaminants and discusses their uniqueness, future prospects, and economic viability. The concern of non-recoverable costs and the recovery of ILs and DESs after their decontamination role is also addressed.

Summary: Due to the ease of tailoring the physicochemical properties, deep eutectic solvents (DESs) have varying capabilities for surfactant self-assembly depending on the surfactant headgroup charge. This study investigated the self-aggregation process of three surfactants (SDS, CTAB, and TX-100) dissolved in DESs composed of a lanthanide salt and urea. The critical aggregation concentration (CAC) was obtained using a fluorescence probe, electrical conductance, and surface tension measurements. The results showed that the CACs varied for different surfactants and compositions of DESs, and the thermodynamic parameters revealed the driving forces for self-aggregation.
