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.

特拉华大学的约翰·拉伯特（John Rabolt）教授和杜邦公司研发实验站的布鲁斯·蔡斯（Bruce Chase）博士正在努力开发一种便携式红外局灶性平面阵列阵列光谱仪，以实时检测气体中的化学和生物剂。 该方法有可能在100微秒的时间尺度上传递红外吸光度信息。 静电纺丝产生的高表面积聚合物将用于浓缩痕量的有毒分析物。 该方法有可能放大和产生因其大小和/或透射率而在气相中无法检测到的气溶胶液滴和颗粒物的红外光谱。 坚固的仪器可以实时采样，并将在国家安全，环境和工业过程监测中提供应用。 该项目中的一个特定目标分析物是Sarin代理。该奖项由NSF和情报界共同支持。数学和物理科学局中打击恐怖主义计划的方法支持基础研究和劳动力发展中的新概念，有可能为国家安全做出贡献。
