A 2D platform was designed and validated for fast screening of milk for deoxynivalenol. The qualitative and quantitative assay of deoxynivalenol in the milk samples was done using a 2D stochastic sensor based on single walled carbon nanotubes modified with [N-(pyridine-4-yl-methyl)]octadec-9-enamide. The working concentration range was between 10 and 10 g mL, with a sensitivity of 5.48 × 10 sgmL, and a limit of determination of 1 fg mL. Recovery values higher than 99.00 % with RSD values lower than 1.00 % were recorded for the determination of deoxynivalenol in cow's and in the vegetarian (coconut milk, soy milk, almond milk) milk.
设计并验证了一个二维平台，用于快速筛选牛奶中的脱氧雪腐镰刀菌烯醇。使用基于单壁碳纳米管的二维随机传感器，对牛奶样品中的脱氧雪腐镰刀菌烯醇进行定性和定量分析，该传感器用[N-(吡啶-4-基-甲基)]十八-9-烯酰胺修饰。工作浓度范围为 10 至 10 g/mL，灵敏度为 5.48×10 sg/mL，检测限为 1 fg/mL。在牛奶（奶牛和素食者的，如椰奶、豆浆、杏仁奶）中测定脱氧雪腐镰刀菌烯醇时，回收率高于 99.00%，相对标准偏差（RSD）低于 1.00%。
