武汉大学的科研人员建立一种基于免疫磁珠分离与双酶系统的新型电化学免疫传感器检测方法,可特异性地检测经组装而成的H9N2亚型禽流感病毒颗粒。研究者将一种酶作为示踪酶标记于免疫磁珠,此免疫磁珠可累积于m-AuE(实验室自行设计的可用于电化学免疫传感的工作电极),同时通过层状组装技术将另一种酶固定于m-AuE;该电极通过简单的清洗程序即可重复利用。研究表明,基于免疫磁 Researchers at Wuhan University have established a novel electrochemical immunosensor detection method based on immunomagnetic bead separation and double enzyme systems to specifically detect particles of the assembled H9N2 subtype of avian influenza virus. Researchers labeled an enzyme as a tracer enzyme to immunomagnetic beads that could accumulate on m-AuE (a lab-designed working electrode that could be used for electrochemical immunosensing), and at the same time, through layered assembly techniques Another enzyme is immobilized on m-AuE; the electrode can be reused with a simple cleaning procedure. Research shows that immunomagnetic-based
