After rapid synergistic cloud point extraction as the pretreatment technology, and high-performance liquid chromatography was carried out, and the analytes in surfactant-rich phase supernatant were detected fluorometrically. Genapol X-080 was specially selected as the extractant, while acetonitrile was the cloud revulsant and synergistic reagent.

High extraction efficiencies (89.2 %−99.3 %) and enhancement factors (16.2 −18.1) of the six bisphenols were achieved.

To address this limitation and enable trace detection, this study presents a G-DNAzyme-mediated biosensor that combines entropy-driven catalytic reactions (EDC) and catalytic hairpin assembly (CHA) to enhance sensitivity and broaden its applicability for detecting trace levels of aflatoxin B1 (AFB1). In this biosensor, AFB1 specifically binds to aptamer, triggering the release of a complementary initiator chain, which activates both EDC and CHA amplification processes. This dual amplification results in the generation of numerous free G-quadruplex sequences, which then bind to hemin, catalyzing a color change in the chromogenic substrate and significantly amplifying the signal. The biosensor demonstrated excellent linearity between the absorbance intensity and logarithm of AFB1 concentrations, with a detection limit (LOD) of 0.47 pM. Furthermore, spiked recovery tests of AFB1 in actual samples showed recovery rates between 96.12 % and 108.50 %, indicating strong accuracy.
