This work proposes a new strategy for the electrochemical quantification of Cu(II) using glassy carbon electrodes (GCEs) modified with nanohybrid multiwall nanotubes (MWCNTs) non-covalently functionalized rationally designed Schiff base containing different groups (SB-dBA). The principle sensing was complexation by that supports MWCNTs at open-circuit potential, followed reduction step −0.600 V and further linear sweep anodic stripping voltammetry (LSASV) in 0.200 M acetate buffer solution pH 5.00. range goes from 10 to 200 μg L−1, sensitivity (0.79 ± 0.07) µA L µg−1 (R2 = 0.991), detection limit 3.3 reproducibility 8.0% same (nine electrodes) 9.0% four nanohybrids. proposed sensor very selective even presence Pb(II), Fe(II), As(III), Cr(III), Cd(II), Hg(II), it successfully used water samples (tap, groundwater, river) without any pretreatment.

Pesticide residues pose significant risks to human health and the environment, emphasizing need for sensitive detection analysis methods. Fluorescence-based sensors, particularly those utilizing aggregation-induced emission (AIE) fluorophores (AIEgens), have demonstrated exceptional performance in this area. This review summarizes key advancements pesticide sensors based on AIEgens, detailing their luminescence mechanisms fluorescence sensing principles. It explores various applications of AIEgens including organic small-molecule nanocomposite metal-organic framework supramolecular fluorescent porous polymer lateral flow immunoassay with specific examples illustrating performance. also discusses current challenges future perspectives development these sensors. We anticipate that will serve as a valuable timely resource researchers working advance application AIEgens-based detection.
