Monitoring of herbicides and pesticides in water, food, and the environment is essential for human health, and this requires low-cost, portable devices for widespread deployment of this technology. For the first time, a wearable glove-based electrochemical sensor based on conductive Ag nano-ink was developed for the on-site monitoring of trifluralin residue on the surface of various substrates. Three electrode system with optimal thicknesses was designed directly on the finger surface of a rubber glove. Then, fabricated electrochemical sensor used for the direct detection of trifluralin in the range of 0.01 μM to 1 mM on the surface of tomato and mulberry leaves using square wave voltammetry (SWV) and difference pulse voltammetry technique. The obtained LLOQ was 0.01 μM, which indicates the suitable sensitivity of this sensor. On the other hand, this sensor is portable, easy to use, and has a high environmental capability that can be effective in detecting other chemical threats in the soil and water environment.

基于触摸指尖的氟乐灵识别：基于可穿戴手套的传感器在环境污染和人类健康控制中的应用

监测水、食品和环境中的除草剂和杀虫剂对人类健康至关重要，这需要低成本的便携式设备来广泛部署这项技术。首次开发了一种基于导电银纳米墨水的可穿戴手套电化学传感器，用于现场监测各种基材表面的氟乐灵残留。直接在橡胶手套的手指表面设计了具有最佳厚度的三电极系统。然后，利用方波伏安法（SWV）和差分脉冲伏安法技术制备了用于直接检测番茄和桑叶表面0.01 μM至1 mM氟乐灵的电化学传感器。获得的 LLOQ 为 0.01 μM，表明该传感器具有合适的灵敏度。另一方面，
