In this study, a flexible glove-based electrochemical sensor as a wearable point-of-use screening tool has been fabricated for defense and food security applications. To design the wearable glove-based sensor, we drew conductive patterns on the fingers of a rubber glove via gold@silver-modified graphene quantum dots (Au@Ag core-shell/graphene quantum dots [GQDs]) nano-ink with optimal thickness. Then, this platform is combined with a portable electrochemical analyzer for on-site detection of trifluralin pesticide in the range of 10 nM to 1 mM with the low limit of quantification (LLOQ) of 10 nM. The high efficiency and distinction of the trifluralin at specified concentrations in real leaf and apple samples were performed by simply touching with the glove and in spikes solution by immersing of fingertips. With their high sensitivity, selectivity, rapid, and easy operation pesticide analysis, these glove-embedded sensors can also be engaged in on-site monitor of other chemical threats and can be expanded to water and environmental samples.

用于快速监测氟乐灵的可拉伸手套传感器：基于可穿戴柔性传感器技术的手套实验室现场识别除草剂新平台

在这项研究中，一种基于手套的柔性电化学传感器作为一种可穿戴的使用点筛选工具已被制造用于国防和食品安全应用。为了设计基于手套的可穿戴传感器，我们通过具有最佳厚度的金@银改性石墨烯量子点（Au@Ag 核壳/石墨烯量子点 [GQDs]）纳米墨水在橡胶手套的手指上绘制导电图案. 然后，将该平台与便携式电化学分析仪相结合，用于现场检测 10 nM 至 1 mM 范围内的氟乐灵农药，定量下限 (LLOQ) 为 10 nM。通过简单地用手套接触并通过浸入指尖在尖刺溶液中进行指定浓度的氟乐灵在真实叶子和苹果样品中的高效和区分。凭借其高灵敏度、选择性、
