SBIR Phase I: Colorimetric Sensor for Real-Time Detection of Nitroaromatic Explosives

这个小型企业创新研究(SBIR)第一阶段项目将开发一种成本效益高、快速反应的传感器，用于检测硝基芳香炸药的存在。它涉及一种独特的化学检测技术，其中一系列染料的色度变化构成了一个信号，很像哺乳动物的嗅觉系统产生的信号；每种染料都是一个交叉响应传感器。这项技术被称为“嗅觉”。该计划旨在评估电子鼻用于检测硝基芳香族爆炸物的灵敏度、特异性和重复性，并将嗅觉技术集成到廉价的便携式监测器中，用于实时检测爆炸物物质。这项工作将导致一种手持、电池供电的设备，用于预防性监视和早期检测这些化合物，从而降低对这里和世界各地的普通公众、公务员和军事人员的风险。

This Small Business Innovation Research (SBIR) Phase I project will develop a cost-effective, fast-acting sensor for detecting the presence of nitroaromatic explosives. It involves a unique chemical detection technology in which colorimetric changes in an array of dyes constitute a signal much like that generated by the mammalian olfaction system; each dye is a cross-responsive sensor. This technology has been dubbed "Smell-Seeing". The program is designed to evaluate the sensitivity, specificity and reproducibility of the electronic nose when used to detect nitroaromatic explosives and to integrate the smell-seeing technology into an inexpensive, portable monitor for real-time detection of explosive substances.This work will result in a hand-held, battery-powered device for preventative surveillance and early detection of these compounds, thereby reducing risk to the general public, public servants and military personnel here and around the world.
