Controlling the stability of colloidal nanoparticles in multicomponent systems is crucial for advancing formulations and separation processes. This study investigates selective agglomeration approach binary mixtures, providing both fundamental insights into stability/agglomeration mechanisms a scalable strategy. First, we established model system comprising gold (Au NPs) ZnS quantum dots (QDs) to assess interparticle interactions. UV-visible spectroscopy revealed that impurities released from QDs, particularly thiol-based ligands unbound Zn ions, triggered aggregation Au NPs depending on their surface stabilizers. Functionalization with bis(p-sulfonatophenyl) phenylphosphine (BSPP) significantly enhanced stability, unpurified BSPP-functionalized exhibiting superior resistance agglomeration. Building these insights, applied separate complex consisting InP/ZnS core–shell QDs byproducts, critical challenge QD synthesis relevant post-processing samples originate large-scale flow synthesis. By systematically tuning ethanol concentration as poor solvent, successfully achieved composition-dependent fractionation. Optical spectroscopic analyses confirmed coarse fractions were enriched while fines mainly contained pure absorption peaks at 605 nm 290 nm, respectively. Photoluminescence spectra further demonstrated redshift fractions, correlating an increase particle size. These results underscore potential scalable, post-synthesis classification method, offering framework controlling strategies systems.

Brain aging is a complex process regulated by genetic, environmental, and metabolic factors, increasing evidence suggests that environmental pollutants can significantly accelerate this interfering with oxidative stress, neuroinflammation, mitochondrial function-related signaling pathways. Traditional studies have focused on the direct damage of macromolecules (e.g., proteins, DNA), while central role senescence-associated small molecules ROS, PGE2, lactate) in early regulatory mechanisms has been long neglected. In study, we innovatively proposed cascade framework "small molecule imbalance-signaling pathway dysregulation-macromolecule collapse", which reveals exacerbate dynamics brain through activation NLRP3 inflammatory vesicles inhibition HIF-1α. Meanwhile, to address technical bottleneck spatiotemporal monitoring, paper systematically reviews cutting-edge detection tools such as electrochemical sensors, genetically encoded fluorescent probes antioxidant quantum dots (AQDs). Among them, AQDs show unique advantages real-time monitoring ROS fluctuations intervention virtue their ultra-high specific surface area, controllable modification, free radical scavenging ability. By integrating multimodal techniques mechanism studies, work provides new perspective for analyzing pollutant-induced lays methodological foundation strategies based networks.
