Abstract

Ochratoxine A is a very stable mycotoxin which cannot be destroyed below 250°C. Found in grains, coffee, grapes, wine, milk, and meat, it can produce kidney damage and cancer. Therefore, a smartphone operated intellingent stochastic miniplatform was designed, characterised, and validated for the on-site screening of milk for fast determination of ochratoxine A. (Z)-N-[2-(4-hydroxyphenyl) ethyl]octadec-9-enamide was used as modifier of a gold matrix for a screen printed stochastic sensor used as sensing tool in the design of the miniplatform. A wide linear concentration range (1.0 × 10−15 − 1.0 × 10−7 mol l‒1) and a low limit of quantification of 1 fmol l‒1 were achieved for the assay of ochratoxin A. Recovery values higher than 99.00% were obtained for ochratoxine A, when the miniplatform was used for the screening of cow’s milk and vegetarian milk.
用于现场筛查牛奶以快速检测赭曲霉毒素 A 的智能手机操作随机微型平台
赭曲霉毒素 A 是一种非常稳定的霉菌毒素,在 250°C 以下无法被破坏。它存在于谷物、咖啡、葡萄、葡萄酒、牛奶和肉类中,可导致肾损伤和癌症。(Z)-N-[2-(4-羟基苯基)乙基]十八-9-烯酰胺被用作丝网印刷随机传感器的金基质改性剂,丝网印刷随机传感器被用作微型平台设计中的传感工具。赭曲霉毒素 A 的检测达到了较宽的线性浓度范围(1.0 × 10-15 - 1.0 × 10-7 mol l-1)和较低的定量限(1 fmol l-1)。
