Electrochemical sensing of nitrofurazone on Ru(bpy)32+ functionalized polyoxometalate combined with graphene modified electrode

Gadolinium molybdate decorated graphitic carbon nitride composite: highly visualized detection of nitrofurazone in water samples

“…Hence, the GCE/g-C 3 N 4 /Gd 2 MoO 6 electrode has the potential for the selective and sensitive detection of NFZ. Moreover, the detection limit of the NFZ at the GCE/g-C 3 N 4 /Gd 2 MoO 6 electrode is lower than that of the other modied electrodes such us, Ag + @UiO-66-NH 2 /CsPbBr 3 /GCE-ECL electrode (LOD = 0.09 mM), 1 Ag-SDS fabricated electrode (LOD = 0.37 mM), 5 poly ACBK/ GCE electrode (LOD = 0.250 mM), 9 [Ru-PMo/PDDAg-GO] 3 electrodes (LOD 50.0 mM), 4 LMNSs/SPCE electrode (LOD = 0.08 mM), 47 Ag 2 S QDs/g-C 3 N 4 electrode (LOD = 0.054 mM), 48 hollow MIL-101/GCE electrode (LOD = 0.01 mM), 2 Ag-NPS@CPE electrode (LOD = 0.012 mM), 3 WS 2 QDs electrode (LOD = 0.055 mM) 49 and PACBK/GCE electrode (LOD = 0.028 mM) 50 exhibit the NFZ detection at long linear response range than other aforementioned modied electrode due to the large surface area as well as the higher electrocatalytic effect.…”

“…3 It has been added to feed to prevent and cure infectious disorders in poultry, livestock, and aquatic sh, and also used as an antiseptic and disinfectant to treat human skin illnesses. 4,5 It is also an anti-infective used to treat or monitor infections of the skin, genitourinary system, eyes, nose, and ears. NFZ residues present in food can be transferred via the food chain to the human body, where chronic intake can cause carcinogenic and teratogenic effects.…”

Design and Evaluation of a ZIF-8/WCNT-Based Electrochemical Sensor for Nitrofurazone Determination in Laboratory Teaching

“…1.1 实验原理 呋喃西林(5-硝基-2-糠醛缩氨基脲，NFZ)是人工合成的硝基呋喃衍生物，广泛用于水产养殖，但 因其具有遗传毒性和致突变性被禁止使用，建立呋喃西林检测方法非常必要。目前，已报道的检测 方法有分光光度法、高效液相色谱法和液相色谱-串联质谱法等 [8,9] 。这些方法存在着繁琐耗时、仪器 设备昂贵、使用大量毒性有机溶剂等不足。相比之下，电化学传感方法具有设备简单、成本低等优 点，在抗生素研究领域受到重视 [10][11][12][13][14] 。各种纳米材料引入起到信号放大作用，被广泛用于电化学传 感器以改善表面结构和电化学性能。 沸石咪唑酯骨架-8 (ZIF-8)是沸石咪唑MOFs材料，由Zn与桥接配体咪唑中的N配位而成，表现出 许多特优性能。由于ZIF-8导电性弱，金属纳米粒子或碳纳米管(WCNT)等可改善ZIF-8弱导电性，提 高电化学传感器性能改善分析方法灵敏度 [10][11][12]…”

Immunosensor of Nitrofuran Antibiotics and Their Metabolites in Animal-Derived Foods: A Review

“…Considerable recoveries when tested in human urine and serum samples. Cai et al ( Cai et al, 2022 ) combined functionalized polyoxometalates with graphene-modified electrodes through layer-by-layer assembly to achieve sensitive detection of NFZ with a LOD as low as 0.08952 μM. Direct low-level detection through real samples was achieved by accelerating its electron transfer modified electrode through [Ru-PMo 12 /PDDA-GO] 3 .…”
