摘要(Abstract)：

环丙沙星(CIP)作为一种广泛使用的氟喹诺酮类抗生素，在食品中的残留可能引发微生物耐药性等潜在风险。开发高灵敏和高选择性的CIP电化学传感器对于食品安全至关重要。本工作制备了一种基于氨基化碳纳米管(CNT-NH_2)/MXene复合材料的新型电化学传感器，可以快速、灵敏地检测CIP。将负电荷的MXene和正电荷的CNT-NH_2的自组装合成CNT-NH_2/MXene复合材料，其中CNT-NH_2的引入起到了层间隔离物的作用，减轻了MXene的堆积。CNT-NH_2与MXene的协同作用使复合材料具有快速的电子传递能力和较大的电化学活性面积，提高了传感器的灵敏度。结果表明，该传感器在0.5～500μmol/L的线性范围内具有良好的检测性能，检测限(LOD)为0.042 7μmol/L。将该传感器应用于鸡蛋样品中CIP残留的检测，检测效果较好，具有积极的推广价值。
