Abstract

As a nutrient partitioning agent and a growth stimulator, ractopamine (RCT) enhances the feed efficiency in animal-based food products and further it is employed clinically in certain pharmaceuticals. Subsequently, metabolites of RCT have long shelf life in animals associated with deleterious repercussions in humans. It is thus, vital to develop an effective design for screening method towards RCT detection to ensure human health, food and environmental safety. Thus, we present an integrate electrocatalyst hydrothermally designed by employing NiCo–LDH (NiCo- Layered Double Hydroxides) and F-HNT (functionalized- Halloysite nanotubes) and further utilized in the electrochemical sensing of RCT. The novelty of the present work shed light upon the unique assembly of the two individual NiCo–LDH and F-HNT components with superior structural features that resulted in a hybrid matrix. The outcomes of CV and i-t analysis under optimum conditions demonstrate outstanding electrochemical performance of the NiCo–LDH/F-HNT modified GCE sensor with a wide linear range 0.003–631 μM and low detection limit 1.1 nM, enhanced selectivity towards the detection of RCT. The uniquely engineered electrode material has therefore been applied to quantitate RCT levels in real-world samples in terms of practical applications.

nico层状双氢氧化物修饰功能化高岭土纳米管复合材料。一种检测莱克多巴胺的高效电催化剂

莱克多巴胺(ractopamine, RCT)作为一种营养分配剂和生长刺激剂，提高了动物性食品的饲料效率，并在临床上应用于某些药物。随后，RCT的代谢物在动物中具有与人类有害影响相关的长保质期。因此，开发一种有效的RCT检测筛选方法设计以确保人类健康、食品和环境安全至关重要。因此，我们提出了一种采用NiCo- ldh (NiCo-层状双氢氧化物)和F-HNT(功能化-埃洛石纳米管)水热设计的集成电催化剂，并将其进一步用于RCT的电化学传感。目前工作的新颖性揭示了两个单独的NiCo-LDH和F-HNT组件的独特组装，具有优越的结构特征，导致混合矩阵。优化条件下的CV和i-t分析结果表明，NiCo-LDH /F-HNT修饰的GCE传感器具有良好的电化学性能，线性范围为0.003 ~ 631 μM，检出限为1.1 nM，对RCT检测的选择性增强。因此，就实际应用而言，独特的工程电极材料已被应用于量化现实世界样品中的RCT水平。
