*** 9761605 Martin This Small Business Innovation Research Phase I project describes the development of a novel array-based chemical microsensor and a dedicated sampling system for the monitoring of chlorinated hydrocarbons in the subsurface. Chlorinated hydrocarbons represent the most prevalent contaminants in the subsurface, threatening the quality of groundwater at aquifers. Existing technology for monitoring these contaminants requires expensive, labor-intensive methods of sample collection and analysis. In the proposed sensor, the chemical and electrical properties of the individual elements of the array will be controlled so that a unique fingerprint will identify each pollutant. The output signals will be integrated into a software-based neural network for analyte identification. The simple design, cost, fabrication, and operation requirements of the proposed sensor will overcome the limitations of other existing array sensors. The development of a low-cost, reliable sampling and monitoring system would reduce the cost associated with sampling and contaminant monitoring, and allow timely continuous information. Also, it will provide the possibility for automated and unattended monitoring of the migration of contaminant plumes, as well as for monitoring contaminants that breach containment operations. Phase I will (i) demonstrate the feasibility of the sensor design, (ii) develop a hand held prototype, and (iii) test contaminated groundwater. During Phase II, a field deployable prototype instrument will be developed and demonstrated. Potential Commercial Applications of the Research: The increasing emphasis on environmental issues, waste reduction, and improved efficiency for industrial processes has underlined the importance of the development of new chemical sensors for field or in-plant use. Specifically, sensors are needed to gauge the effectiveness of remediation efforts, to effect waste minimization, and to detect the presence of toxic, hazardous, or otherwise regu lated chemicals in waste effluents, drinking water, and other environmental systems. In addition, this proposed sensor will find wide application in the food, drink and perfume industries for the determination of odors and aromas, as well as in the clinical (e.g., breath monitor) and agronomic industries (e.g., detection of pesticides). ***

*9761605马丁这个小型企业创新研究第一阶段项目描述了一种新型的基于阵列的化学微传感器和用于监测地下氯代烃的专用采样系统的开发。氯代烃是地下最普遍的污染物，威胁着含水层的地下水质量。现有的监测这些污染物的技术需要昂贵的、劳动密集型的样本收集和分析方法。在拟议的传感器中，阵列中各个元素的化学和电学性质将受到控制，以便唯一的指纹将识别每种污染物。输出信号将被集成到基于软件的神经网络中，用于分析物识别。该传感器的设计、成本、制造和操作要求简单，将克服现有阵列传感器的局限性。开发低成本、可靠的采样和监测系统将减少与采样和污染物监测相关的成本，并使及时、连续的信息成为可能。此外，它还将提供自动和无人值守监测污染物羽流迁移的可能性，以及监测违反安全壳作业的污染物的可能性。第一阶段将(I)论证传感器设计的可行性，(Ii)开发手持原型，以及(Iii)测试受污染的地下水。在第二阶段，将开发和演示可现场部署的原型仪器。这项研究的潜在商业应用：对环境问题、减少废物和提高工业过程效率的日益重视，突显了开发用于现场或工厂内使用的新化学传感器的重要性。具体地说，需要传感器来衡量补救工作的有效性，以实现废物最小化，并检测废物流出物、饮用水和其他环境系统中是否存在有毒、危险或其他有害化学物质。此外，这种拟议的传感器将在食品、饮料和香水行业中获得广泛应用，用于气味和香气的测定，以及临床(例如呼吸监测器)和农艺行业(例如农药检测)。***
