Abstract#1230189Sadik, Omowunmi A.Intellectual MeritNovel environmental nanoparticle analyzers and methods are needed to assess the risks posed by engineered nanomaterials. Addressing the complex and critical issues surrounding the responsible development of nanotechnology is important both for society and the environment. The progress of society as technological advances are introduced has often resulted in the simultaneous emergence of adverse effects either for human health, the ecosystem or both. The emerging field of environmental nanotechnology is a critical research area, and one which would greatly benefit from a rapid EAGER support. Hence, the immediate goal of this research is to develop an environmentally-relevant, portable nanoparticle analyzer which can measure various levels of nanomaterials directly from pure standards, simulated matrices and real-world samples. The proposed research is expected to bridge the knowledge and methodology gaps associated with the potential environmental health and safety (EH&S) issues of nanomaterials. The resulting technology should provide information about the size or shape of the nanoparticle, which are important factors for determining toxicity; as well as distinguish them from naturally-occurring particles.The research will make use of a new class of flexible, optically transparent conducting nanoporous membranes to simultaneously capture, isolate and detect engineered nanomaterials. Selected metal oxides and carbon based nanomaterials will be tested by integrating electrochemistry, polyamic acid membranes and tangential flow filtration to create a system that can be used in situ.Broader ImpactsA major outcome of this project is an environmentally-relevant portable sensor system which can measure the levels of various nanomaterials directly from the environmental samples and possibly remedy them via filtration. The approach provides information regarding the size and other physical parameters of the nanomaterials, which are important in determining nanomaterials toxicity. This approach can be of great benefit for environmental and security applications because the portable analyzers can be deployed in many places to safeguard the environment, public safety, and security. This research will provide excellent training experience for graduate students as well as train undergraduate minority students who will gain exposure to field environmental analysis. Further, this research will support the enhancement of existing graduate and undergraduate courses including Chemistry and the Environment (CHEM 552C/482C) and Sensors and Bioelectronics (CHEM 424/524). Other dissemination plans include presentations at national conferences and joint publications in peer-reviewed journals in related fields.

摘要#1230189Sadik，Omowunmi A.知识产权需要新型环境纳米颗粒分析仪和方法来评估工程纳米材料带来的风险。解决围绕负责任的纳米技术发展的复杂和关键问题对社会和环境都很重要。随着技术进步的引入，社会的进步往往导致同时出现对人类健康、生态系统或两者的不利影响。环境纳米技术的新兴领域是一个关键的研究领域，这将大大受益于快速EAGER的支持。因此，本研究的直接目标是开发一种与环境相关的便携式纳米颗粒分析仪，可以直接从纯标准品，模拟基质和真实样品中测量各种水平的纳米材料。拟议的研究预计将弥合与纳米材料潜在的环境健康和安全（EH S）问题相关的知识和方法差距。该技术将提供有关纳米颗粒大小或形状的信息，这是确定毒性的重要因素;以及将它们与自然产生的颗粒区分开来。该研究将利用一类新的柔性，光学透明的导电纳米多孔膜来同时捕获，分离和检测工程纳米材料。选定的金属氧化物和碳基纳米材料将通过整合电化学，聚酰胺酸膜和切向流过滤来测试，以创建一个可以在原位使用的系统。更广泛的影响这个项目的一个主要成果是一个与环境相关的便携式传感器系统，可以直接从环境样本中测量各种纳米材料的水平，并可能通过过滤进行补救。该方法提供了有关纳米材料的尺寸和其他物理参数的信息，这些信息对于确定纳米材料的毒性非常重要。这种方法对于环境和安全应用非常有益，因为便携式分析仪可以部署在许多地方，以保护环境，公共安全和安全。这项研究将提供优秀的培训经验，研究生以及培养本科少数民族学生谁将获得接触现场环境分析。此外，这项研究将支持现有的研究生和本科生课程，包括化学与环境（化学552 C/482 C）和传感器和生物电子学（化学424/524）的增强。其他传播计划包括在国家会议上发言和在相关领域的同行评审期刊上联合发表文章。
