SGER: Amplification & Detection of Trace Quantities of Biological and Chemical Agents using High Surface Area Membranes and an Ultrafast Planar Array IR Spectrograph

特拉华大学的约翰·拉博尔特教授和杜邦公司研发实验站的布鲁斯·蔡斯博士正在致力于开发一种便携式红外焦平面阵列光谱仪，用于实时检测气体中的化学和生物制剂。该方法有可能在100‘S微秒的时间尺度上传递红外吸收信息。通过静电纺丝生产的高表面积聚合物将被用于浓缩微量有毒分析物。该方法有可能放大和产生气溶胶液滴和颗粒的红外光谱，而气相中由于其尺寸和/或透过率而无法检测到这些颗粒。这种坚固耐用的仪器可以实时采样，将在国家安全、环境和工业过程监测中应用。该项目中的一个特定目标分析物是沙林替代品。该奖项由美国国家科学基金会和情报界共同支持。数学和物理科学局的反恐方法方案支持基础研究和劳动力发展方面的新概念，有可能对国家安全作出贡献。

Professor John Rabolt of the University of Delaware and Dr. Bruce Chase of Dupont Corporate R&D Experimental Station are working to develop a portable infrared focal plane array spectrometer for the real-time detection of chemical and biological agents in gases. The method has the potential to deliver infrared absorbance information on a time scale of 100's of microseconds. High surface area polymers produced by electrospinning will be utilized to concentrate trace quantities of toxic analytes. The method has the potential to amplifiy and produce IR spectra of aerosol droplets and particulates that cannot be detected in the gas phase due to their size and/or transmissivity. The rugged instrument can sample in real time and would have applications in national security, environmental and industrial process monitoring. One specific target analyte in this project is a sarin surrogate.This award is supported jointly by the NSF and the Intelligence Community. The Approaches to Combat Terrorism Program in the Directorate for Mathematics and Physical Sciences supports new concepts in basic research and workforce development with the potential to contribute to national security.
