    摘要:

    目的 为实现T-2毒素的现场快速筛查,建立聚集诱导发光荧光免疫层析试纸条测定玉米中T-2毒素的分析方法。方法 采用溶胀法制备聚集诱导发光荧光微球,通过静电吸附偶联抗体,得到免疫探针。通过优化试验参数,构建荧光免疫层析试纸条。结果 构建的聚集诱导发光荧光免疫层析法具有良好的线性关系(0.10~5.00 ng/mL),回归方程为y=-0.571 41 lg(x)+0.750 88(R2=0.967 5),方法检测限为0.09 ng/mL,加标回收率为81.82%~92.46%,变异系数低于10%。结论 该方法准确性好,灵敏度高,适用于玉米中T-2毒素的现场大批量筛查。

    Abstract:

    Objective To achieve rapid on-site screening of T-2 toxin and establish an analytical method for the determination of T-2 toxin in corn using aggregation-induced emission (AIE) immunochromatographic test strips.Methods Aggregation-induced emission fluorescent nanoparticles (AIEFNPs) were prepared by the swelling method, and antibodies were coupled via electrostatic adsorption to obtain immune probes. The fluorescent immunochromatographic test strips were constructed by optimizing the experimental parameters.Results The constructed AIE fluorescent immunochromatographic method exhibits a good linear relationship in the range of 0.10~5.00 ng/mL. The regression equation was y=-0.571 41 lg(x)+0.750 88 (R2=0.967 5), with a method detection limit of 0.09 ng/mL. The spiked recovery rates range from 81.82% to 92.46%, and the coefficient of variation is less than 10%.Conclusion This method demonstrates good accuracy and high sensitivity, making it suitable for on-site large-scale screening of T-2 toxin in corn.
