SPR生物传感技术在农产品安全检测中的应用

表面等离子共振作为近几年在国内发展起来的一种检测技术,具备检测样品用量少、灵敏度高、检测速度快等优点,已被用于环境检测、医疗诊断、药物筛选、蛋白质组学、基因组学等诸多领域。随着技术的发展,广大学者将其与生物技术结合起来,在传感芯片表面修饰不同的特异性抗原抗体及信号放大因子,将表面等离子共振技术不断应用到农产品安全的检测中。通过介绍该技术在农产品中农残药残、动物疾病、微生物、食品添加剂、重金属及转基因检测的应用情况,以期使读者深入了解表面等离子共振技术在食品安全检测的发展现状,为其在该领域的进一步发展提供可以借鉴的资料。

Applications of SPR Biosensing Technology in Agricultural Products Safety Detection

Surface plasmon resonance (SPR) as a novel technology has advantages of small sample volumes, high sensitivity and fast detection speed, which is widely applied in environmental detection, medical diagnosis, drug screening, proteomics, genomics and many other fields. With its development, SPR is combined with biotechnology, then modified by specific antigen, antibody and signal amplification factor, and widely used in safety detection of agricultural products. The paper introduces the application of SPR in detection of pesticide and medicine residues, animal disease, microbe, food additives, heavy metal and transgenic test in agricultural products. The study could provide certain references for understanding the development status of SPR in food safety test.
