This Small Business Innovation Research (SBIR) Phase I project will develop a micro/nano fluidic proteomic platform for pathogen detection and identification. The system is based on the use of high-resolution, two-dimensional (2-D) protein separations in disposable microfluidic chips to generate protein expression maps which may be used to identify biomarker patterns unique to specific pathogens. Effective technologies for the early detection and identification of biological warfare agents are of critical and growing importance. The novel miniaturized detection platform will be capable of meeting key requirements for universal pathogen detection with the ability to identify bacterial, viral, and protein toxin agents in a single detection platform. The system will provide identification within a short 15 minute cycle time, significantly faster than comparable microarray technologies. Furthermore, it will not employ biologically active reagents for its operation and will not require a priori knowledge of which pathogens may be present in a sample. If successful, the proposed technology will provide a unique solution for rapidly identifying environmental pathogens, with benefits for a wide range of field-deployable applications. Further miniaturization employing nanoscale detection channels with confocal scanning microscopy will enable protein profiling at the single molecule level for ultra-sensitive early pathogen detection. In addition to the need for improved pathogen detection for antiterrorism applications, there are over two million emergency response personnel located at over 90,000 public health and safety facilities who are effectively on the front lines of homeland defense, and who will directly benefit from cost-effective technologies to quickly detect or dismiss potential biowarfare threats. It is particularly vital for these personnel to have access to detection tools capable of broad spectrum pathogen detection without the need for priori knowledge of which pathogens may be present. In addition, rapid, accurate bacterial identification is critically important in applications outside of biowarfare defense. Industries which will benefit from these developments include disease diagnosis, prediction of emerging health hazards, monitoring potential food contamination, and bioprocess regulation. Furthermore, the technology in this effort will offer benefits to the biopharmaceutical industry as a proteomics tool for biomarker identification and drug discovery.

这个小型企业创新研究(SBIR)第一阶段项目将开发一个用于病原体检测和鉴定的微纳流控蛋白质组平台。该系统基于使用一次性微流控芯片中的高分辨率二维(2-D)蛋白质分离来生成蛋白质表达图谱，该图谱可用于识别特定病原体特有的生物标志物模式。早期发现和识别生物战剂的有效技术至关重要，而且日益重要。新型小型化检测平台将能够满足通用病原体检测的关键要求，能够在单一检测平台中识别细菌、病毒和蛋白质毒素。该系统将在短15分钟的周期时间内提供鉴定，比可比的微阵列技术快得多。此外，它不会使用生物活性试剂进行操作，也不需要事先知道样本中可能存在哪些病原体。如果成功，拟议的技术将为快速识别环境病原体提供一种独特的解决方案，并有利于广泛的现场部署应用。利用共聚焦扫描显微镜的纳米级检测通道的进一步小型化将使蛋白质图谱能够在单分子水平上进行超灵敏的早期病原体检测。除了需要为反恐应用改进病原体检测外，在90,000多个公共卫生和安全设施中还有200多万应急人员，他们有效地站在国土防御的第一线，他们将直接受益于具有成本效益的技术，以快速检测或消除潜在的生物武器威胁。对这些人员来说，特别重要的是能够获得能够进行广谱病原体检测的检测工具，而不需要先验地知道可能存在哪些病原体。此外，快速、准确的细菌鉴定在生物武器防御之外的应用中至关重要。将从这些发展中受益的行业包括疾病诊断、新出现的健康危害的预测、监测潜在的食品污染和生物过程监管。此外，这项工作中的技术将作为生物标记物识别和药物发现的蛋白质组学工具，为生物制药行业带来好处。
