DNA芯片已成为一个病原体检测的有力工具。1-5例如，已被证明的能力类型和亚型流感病毒的例子很多。6-11识别和亚型流感DNA芯片应用在公共健康和诊所，以便及早发现，迅速介入，并最大限度地减少流感大流行的影响。传统的荧光是目前最常用的基因芯片检测方法。然而，由于基因芯片技术对临床使用过程，取代昂贵的仪器，成本低的检测技术表现出相似的性能特点，荧光将使芯片检测更具吸引力和成本效益。 ampliPHOX比色法检测技术是用于研究中的应用，和传统荧光11的幅度内之一为了一个近似的10倍仪器成本较低的优势，比焦荧光微阵列芯片扫描仪需要与主要的检测限，检测。另一个优点是体积小巧，仪器的可移植性和灵活性允许不同于传统的荧光仪器。因为聚合技术是不是天生荧光检测线性的，但是，它是最好的适合密度较低的芯片应用中存在一定的顺序是/没有答案所需，如病原体检测阵列。目前最大的现货密度与ampliPHOX检测兼容〜1800点/阵列。由于现场密度的限制，高密​​度微阵列不适合ampliPHOX检测。 在这里，我们目前作为一个信号放大方法对流感病毒的检测和表征（流感集成电路芯片）开发的低密度芯片ampliPHOX比色法检测技术。虽然这个协议使用一个特定的应用程序，任何芯片，结合生物素化的目标，可以标记，并以类似的方式检测ampliPHOX检测流感集成电路芯片（DNA芯片）。被捕获的芯片设计和生物素化的目标是用户的责任。一旦阵列上已捕获生物素化的目标，ampliPHOX检测可以进行与链霉亲和标签的共轭（ampliTAG）的数组，第一个标记。 （ampliPHY）使用ampliPHOX读者仪器，聚合单体溶液的光曝光后只发生在含有ampliTAG标记的目标地区。聚合物形成一种无毒的解决方案，以改善视觉对比度，成像和使用的一个简单的软件程序包（ampliVIEW）分析，随后可沾上。从整个联合国提取样本流感集成电路芯片检测结果可在约6个小时，和上面所述的ampliPHOX检测步骤，可以在大约30分钟完成。
