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

小企业创新研究（SBIR）第一阶段项目将开发一种具有成本效益的快速传感器，用于检测硝基芳香族炸药的存在。它涉及一种独特的化学检测技术，其中染料阵列中的比色变化构成了一种信号，非常类似于哺乳动物嗅觉系统产生的信号;每种染料都是一种交叉响应传感器。这项技术被称为“嗅觉观察”。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、特异性和可重复性，并将嗅觉观察技术整合到一个廉价的便携式监测器中，以实时检测爆炸物质，这项工作将产生一个手持式电池供电装置，用于预防性监测和早期检测这些化合物，从而减少对公众的风险，公务员和军事人员在这里和世界各地。

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.
