The analysis of glyphosate is essential to agricultural production, environment protection and public health. Herein, we proposed a fast and convenient "on-off-on" fluorescence platform for sensitive detection of glyphosate Cu modulated g-CN nanosheets. The fluorescence of the system was quenched by Cu. With the presence of glyphosate, the fluorescence could be restored due to the formation of Cu- glyphosate complex. The proposed method was cost-effective with label-free and enzyme-free. Moreover, it exhibits high sensitivity with a low detection limit of 0.01 μg/ml. Furthermore, the proposed method has been successfully monitored glyphosate in real samples.
草甘膦的分析对农业生产、环境保护和公众健康至关重要。在此，我们提出了一种快速便捷的“开-关-开”荧光平台，用于灵敏检测草甘膦——铜调控的g-CN纳米片。该体系的荧光被铜淬灭。在草甘膦存在的情况下，由于形成了铜-草甘膦络合物，荧光得以恢复。所提出的方法具有成本效益，无需标记和酶。此外，它具有高灵敏度，检测限低至0.01μg/ml。此外，所提出的方法已成功用于实际样品中草甘膦的监测。
