Detection of influenza virus by a biosensor based on the method combining electrochemiluminescence on binary SAMs modified Au electrode with an immunoliposome encapsulating Ru (II) complex.
针对流感感染即时检测(POCT)因灵敏度低而易出现假阴性的问题,本文报道了一种基于电化学发光(ECL)的免疫传感器,用于检测甲型流感病毒 A(H1N1)。该传感器采用包封三(2,2′-联吡啶)钌(II)配合物的免疫脂质体作为发光标记,病毒与固定在自组装单分子层(SAMs)上的血凝素(HA)肽在脂质体表面抗体的免疫反应中发生竞争。所用...
