| 摘 要： | 为了实现对于环境中抗生素恩诺沙星与诺氟沙星的同时快速灵敏检测,本研究基于间接竞争免疫反应模式及荧光全内反射原理,以本课题组自主研发的平面波导生物传感器为平台,建立了恩诺沙星和诺氟沙星的同时快速检测方法.通过对抗体浓度、pH及钙离子浓度的优化,提高了检测方法的灵敏度,结果表明,恩诺沙星的检测限为0.34μg·L~(-1),诺氟沙星的检测限为0.14μg·L~(-1).在单物质检测的基础上,首次实现了基于平面波导传感器的两种抗生素同时检测,检测周期仅15 min,检测限为0.06μg·L~(-1).本研究从理论上分析了同时检测时检测限下降、灵敏度提高的原因,为利用生物传感器法同时检测抗生素提供了理论指导及技术支撑.
