DESCRIPTION (provided by applicant): The objective for this Phase II application is to develop a cartridge-based automated molecular diagnostic platform to rapidly and cost-effectively detect and identify influenza viruses. The system will automate all key functions for sample processing including extraction, amplification, colorimetric detection on a low- density microarray, and image/result interpretation. The idea is to make the system easy to use so that personnel with no PCR or microarray experience could obtain an unequivocal answer with minimal hands- on time. The motivation for the proposed work is the tremendous impact influenza viruses have on human and animal health and the need for rapid, inexpensive tools for strain surveillance. The intent is to significantly enhance influenza virus surveillance by providing a new tool to affordably and rapidly identify influenza viruses without expertise in PCR methods and without exclusive reliance on existing, sometimes poor performing, rapid immunoassays. The marketing plan involves providing the instrument to customers at no capital cost (i.e., the "reagent rental" concept). Therefore, the instrument will be designed with simplicity and low cost in mind. Our market entry point will be influenza surveillance sites, such as state public health labs, where the FluChip assay could be used to track viruses without the need to diagnose patients. Long term, we will use data acquired in these early studies to formulate an FDA submission for 510(k) clearance for use as an in vitro diagnostic. PUBLIC HEALTH RELEVANCE: The objective of the proposed work is to build on the success achieved in Phase I for rapidly identifying influenza viruses by developing a cartridge based system for automated and self-contained sample processing, including extraction, amplification, and colorimetric detection on a low-density microarray.

描述(由申请人提供)：这一第二阶段申请的目标是开发一种基于试剂盒的自动化分子诊断平台，以快速、经济有效地检测和识别流感病毒。该系统将自动化样品处理的所有关键功能，包括提取、放大、低密度微阵列上的比色检测以及图像/结果解释。这个想法是为了让该系统易于使用，这样没有聚合酶链式反应或微阵列经验的人员可以在最短的动手时间内获得明确的答案。这项拟议工作的动机是流感病毒对人类和动物健康的巨大影响，以及需要快速、廉价的病毒株监测工具。其目的是通过提供一种新的工具，以负担得起的价格快速识别流感病毒，而不需要在聚合酶链式反应方法方面的专业知识，也不完全依赖现有的、有时表现不佳的快速免疫分析，从而显著加强流感病毒监测。营销计划包括免费向客户提供仪器(即“试剂租赁”概念)。因此，该仪器的设计将考虑到简单和低成本。我们的市场切入点将是流感监测地点，如国家公共卫生实验室，在那里，荧光芯片分析可以用于跟踪病毒，而不需要诊断患者。从长远来看，我们将使用在这些早期研究中获得的数据来制定FDA提交的510(K)许可用于体外诊断。 与公共卫生相关：拟议工作的目标是在第一阶段取得的成功的基础上，通过开发一种基于试剂盒的系统进行自动化和自给自足的样本处理，包括在低密度微阵列上进行提取、扩增和比色检测，从而快速识别流感病毒。
