Development of a Magnetic Nanoparticles-Based Screen-Printed Electrodes (MNPs-SPEs) Biosensor for the Quantification of Ochratoxin A in Cereal and Feed Samples.
本研究开发了一种基于磁性纳米颗粒和丝网印刷电极(MNPs-SPEs)的电化学生物传感器,用于谷物和饲料样品中赭曲霉毒素A(OTA)的快速灵敏检测。作者优化了三种磁性纳米颗粒酶联免疫吸附测定(MNPs-ELISA)体系,并结合丝网印刷电极(SPEs)增强信号检测与灵敏度。优化条件下,校准曲线为y=0.3372x+0.8324(R2=0...
