Heavy metal pollution has posed a serious threat to the ecological environment and human health. Thus, development of accurate effective methods for their detection is crucial. In this study, novel electrochemical sensor was fabricated detect Cu2+ Hg2+, based on N-doped carbon nanotube-wrapped Ni nanoparticle (Ni@N-CNT) sensing material, which derived from pyrolysis Ni2+ doped ZIF-8. For electrode material design, packaging structure not only protected encapsulated nanoparticles corrosion in acid electrolyte but also provided excellent electro-catalytic activity electrical conductivity by controlling size. Thanks overall performance Ni@N-CNT composite, proposed exhibited analytical Hg2+ detection, with ultra-low limits 33.3 ng⋅L-1 ng⋅L-1, respectively. The demonstrated good repeatability, reproducibility selectivity. addition, method successfully applied analysis actual Chinese cabbage samples satisfactory recovery, confirming its practical applicability.

We developed a sensor consisting of V2O5 nanorods and reduced graphene oxide (rGO) nanocomposite (V2O5/rGO) with immobilized DNA aptamers (Apt-NH@V2O5/rGO) for the sensitive electrochemical detection Hg (II). The anchored on rGO nanosheets were synthesized using hydrothermal method. was analyzed by various powerful physical methods that include X-ray diffraction (XRD), energy-dispersive spectroscopy (EDX), field emission scanning electron microscopy (FE-SEM), Raman spectroscopy, Brunauer-Emmett-Teller (BET) method, Fourier transform infrared (FTIR). FE-SEM disclosed nanorod-like structure uniform anchoring nanosheet. Moreover, BET results showed V2O5/rGO possesses excellent porosity. Furthermore, glassy carbon electrode (GCE) modified Apt-NH@V2O5/rGO used Hg(II) differential pulse voltammetry (DPV). aptasensor exhibited sensitivity selectivity toward detection, limit (LOD) 5.57 nM, which is below maximum permissible established WHO rivers (30 nM). also significant stability good repeatability.

Acetaminophen (ACP), a common analgesic and antipyretic medication, can harm the liver when overdosed its metabolites contaminate environment, so it is necessary to monitor concentration precisely reliably. In this work, we successfully synthesized cerium oxide/nitrogen-doped reduced graphene oxide (CeO 2 /N-rGO) composite nanomaterials using one-step hydrothermal method. Using nanomaterials, created an electrochemical sensing detection platform for ACP detection. The materials were characterized by scanning electron microscopy, transmission X-ray diffraction, Fourier transform infrared spectroscopy, Raman photoelectron spectroscopy. constructed sensor exhibits good ability under synergistic effect of CeO N-rGO. Under optimal experimental conditions, displayed linear range 1 ∼ 200 μ M lowest limit 0.79 M, exhibiting outstanding selectivity, stability, repeatability. Furthermore, was effectively applied detect in tap water samples, which offers wide possible applications actual sample testing.
