ABSTRACTObjective:The proposed research will develop sensors that are capable of detecting improvised explosives based on peroxides. The ever-increasing use of such explosives by terrorist organizations and the paucity of suitable detection devices make this an important objective. Intellectual Merit:This project will take successful technology developed for neutralization of terrorist explosives and apply it to the development of sensors for the detection of explosives. The sensors that will be developed will be atypical because they will be capable of identifying both peroxide-based explosives and conventional nitroorganic explosives. The developed technology will also offer a solution to detecting and eliminating peroxides that form in laboratory solvents. The sensor devices that will be developed will range from very sensitive and robust electronic colorimetric, and fluorescent sensors to simple test strips and inks that can confirm the identity of peroxide explosives.Broader Impacts, Technological: The developed technology could be modified in future research to detect other chemicals by changing the surface catalysts. The experimentation will also advance our understanding of nanoparticle synthesis, reactivity, and surface properties. The research will likely have a widespread and lasting positive impact on the safety and use of laboratory solvents, especially in the area of trace analysis.Broader Impacts, Educational: The students will undergo rotation through the two constituent laboratories to gain experience in all aspects of the proposed research. The project will also provide lectures in nanotechnology in conjunction with the Oklahoma Nanonet Initiative (a NSF EPSCOR project. Public outreach will also be conducted through a web-site and general lectures concerning nanotechnology presented at local high schools and other venues such as AP Teacher Training Institutes. A contribution will also be made to Stillwater's Children's Museum Without Walls that takes displays to school.

摘要目的：本研究将开发一种能够检测基于过氧化物的简易爆炸物的传感器。恐怖主义组织越来越多地使用这种爆炸物，而且缺乏适当的探测装置，因此这是一个重要的目标。知识专长：该项目将采用为消除恐怖主义爆炸物而开发的成功技术，并将其应用于开发探测爆炸物的传感器。将研制的传感器将是非典型的，因为它们将能够识别过氧化物基爆炸物和常规硝基有机爆炸物。开发的技术还将提供检测和消除实验室溶剂中形成的过氧化物的解决方案。将开发的传感器设备将包括非常灵敏和强大的电子比色和荧光传感器，以及可以确认过氧化物爆炸物身份的简单测试条和墨水。更广泛的影响，技术：开发的技术可以在未来的研究中进行修改，通过改变表面催化剂来检测其他化学品。该实验也将促进我们对纳米颗粒合成、反应性和表面性质的理解。该研究可能会对实验室溶剂的安全性和使用产生广泛而持久的积极影响，特别是在痕量分析领域。更广泛的影响，教育：学生将在两个组成实验室进行轮换，以获得拟议研究的各个方面的经验。该项目还将与俄克拉荷马州纳米网倡议（NSF EPSCOR项目）一起提供纳米技术讲座。还将通过网站和在当地高中和AP教师培训机构等其他场所举办的有关纳米技术的一般讲座进行公众宣传。一个贡献也将作出静水的儿童博物馆没有墙壁，采取显示到学校。
