Abstract Silver orthophosphate doped with flower-like MoS2/BiFeO3 binary composite was developed for the augmented and precise sensing of the antibiotic tetracycline. The in-situ developed silver orthophosphate modified composite showed excellent electrocatalytic activity due to its low resistance which favoured the redox probe mechanism. The limit of detection and the linear range of the composite were found as 4.57 picomolar (pM) and 10 to 90 pM corroborating the pronounced sensing capacity. The practical application of the sensor was analyzed with liquid milk samples spiked with tetracycline. More than 97 % of tetracycline was detected which established its high demand in the analytical industry.

具有增强活性的磷酸银基花状 MoS2/BiFeO3 纳米复合材料用于检测四环素

摘要 掺杂花状 MoS2/BiFeO3 二元复合物的正磷酸银被开发用于增强和精确感测抗生素四环素。原位开发的正磷酸银改性复合物由于其低电阻而显示出优异的电催化活性，这有利于氧化还原探针机制。发现复合材料的检测限和线性范围为 4.57 皮摩尔 (pM) 和 10 到 90 pM，证实了显着的传感能力。该传感器的实际应用通过添加四环素的液态奶样品进行了分析。检测到超过 97% 的四环素，这确立了其在分析行业的高需求。
