SBIR Phase II: Hand-Held Device for PPB-level Water Analysis

这个小企业创新研究（SBIR）二期项目将在OndaVia？美国水污染物检测技术从概念验证到商业原型。作为微流体设计方面的专家，OndaVia利用其创新技术制造设备，在现场提供近实时，精确的水分析。我们第一阶段的SBIR项目目标是证明在微流控通道内使用嵌入式表面增强拉曼光谱（SERS）区域检测十亿分之一水平水污染的可行性。以优异的成绩达到的目标第二阶段工作的目标是建立一个原型水分析系统，其预期结果将为将该专有检测技术快速整合到OndaVia？S系列分析仪器。这项研究的更广泛的影响是强调世界正在耗尽“质量”的信念。水。水库正在枯竭，地下水经常因石油开采而受到污染，每天都在湖泊和河流中发现新的工业污染物。典型的分析需要在现场收集样本并将样本运送到测试实验室；水监测机构依赖于这些外包实验室，而这些实验室的运输和处理时间可能需要数天才能产生结果，在社区健康受到威胁时浪费了宝贵的时间。现场准备的实时测量工具可以检测到十亿分之一或更高水平的各种化合物，这将是水测试工具箱中强大、有价值和必要的补充。

This Small Business Innovation Research (SBIR) Phase II project will move OndaVia?s water contaminant detection technology from proof-of-concept to commercial prototype. As experts in microfluidic design, OndaVia uses its innovations to manufacture devices that provide near real-time, precise water analysis in the field. Our Phase I SBIR project goal was to prove the feasibility of detecting 100 part-per-billion-level water contamination using an embedded surface-enhanced Raman spectroscopy (SERS) region within a microfluidic channel?a goal achieved with excellent results. The objective of this Phase II effort is to build a prototype water analysis system, the anticipated results of which will set the stage for rapid incorporation of this proprietary detection technology into OndaVia?s line of analytical instruments.The broader impacts of this research are emphasized by the belief that the world is running out of ?quality? water. Reservoirs are depleting, ground water is frequently contaminated through petroleum extraction, and new industrial contaminants are found in lakes and rivers every day. Typical analysis requires collecting a sample in the field and shipping the sample to a testlaboratory; water monitoring agencies depend upon these outsourced laboratories where transport and processing time can take days to produce results, wasting precious time when the health of a community is at stake. Field-ready, real-time measurement tools that detect a wide array of compounds at a parts-per-billion or better level would be a powerful, valuable, and necessary addition to the water testing toolbox.
