We introduce a sensitive, rapid, label-free and general fluorescent method for the determination of tartrazine by competitive binding to reduced graphene oxide (rGO) against fluorescein, and the fluorescence recovery upon fluorescein desorption from rGO provides a quantitative readout for tartrazine, giving a detection limit of 0.53 ng mL(-1).
我们介绍了一种灵敏、快速、无需标记且通用的荧光法,用于通过与还原氧化石墨烯(rGO)竞争结合来测定柠檬黄,而当荧光素从 rGO 上解吸时荧光恢复提供了柠檬黄的定量读数,检测限为 0.53ng mL(-1)。
