The increased environmental presence of micro-/nanoplastics (MNPLs) and the potential health risks associated with their exposure classify them as pollutants special concerns. Consequently, there is an urgent need to investigate secondary MNPLs. In this context, using "true-to-life" MNPLs, resulting from laboratory degradation plastic goods, may be a sound approach. These non-commercial MNPLs must labeled track presence/journeys inside cells or organisms. Because cell internalization commonly analyzed fluorescence techniques, use fluorescent dyes method label them. Five different compounds comprising two chemical (Nile Red Rhodamine-B), one optical brightener (Opticol), industrial (Amarillo Luminoso iDye PolyPink) were tested determine for such applications. Using commercial standards polystyrene nanoplastics (PSNPLs) average size 170 nm, characteristics selected absence impact on viability, specificity staining, no leaching, lack interference other fluorochromes analyzed. Based overall data obtained in wide battery assays performed, PolyPink exhibited most advantages, respect compounds, was effectively advantages confirmed proposed protocol, labeling titanium-doped PETNPLs (obtained milk PET bottles), example NPLs. results usefulness detecting internalization.

A charge transfer gel from a cetyltrimethylammonium bromide (CTAB) and an additive 6-aminocaproic acid (6-ACA), in two-component solvent mixture at critical composition of 3 : 1 v/v water toluene is reported. The pale yellow colour the arising interactions between amine group (–NH 2 ) hexylamine ammonium ion (N + CTAB was confirmed after performing set trial experiments with CTAB-heptanoic CTAB-hexylamine systems. process gelation, phase development its microstructure were investigated using spectroscopy, microscopy, small-angle X-ray scattering (SAXS) techniques. formed lamellar organization while preserving loose-packed arrangement bilayer 6-ACA molecules, maintaining H-bonding along significant interactions. SAXS pattern revealed distinct crystalline form gel, indicating stable characterized by alternating layers amorphous structures. This unique gelation nature inferred interplanar spacings, demonstrating non-conducive properties highly polar solvents such as methanol ethanol, well less like cyclohexane carbon tetrachloride, when organic polarity altered presence mixed amphiphilic system.
