Nanoporous Solid-Contact Sensors /OISE

该项目由国际科学与工程办公室支持，通过美国-埃及联合科学和技术基金，并通过分析和表面化学方案通过国家科学基金共同评估。该项目由明尼苏达大学双城分校的Philippe Buhlmann Andreas Stein在美国进行，并开发了固体接触电位传感器，该传感器通过使用3-D有序大孔碳作为电极材料克服了传统电极的不稳定性和漂移缺点。该项目利用了4个参与团体的独特资格，即，Abbas小组（埃及）在电位传感器方面的专业知识，以及Stein小组在使用共价连接到聚合物上的离子载体方面的专业知识，Buhlmann小组在这些碳传感器中使用选择性的、防污的氟相的经验，和Abdel Ghaffar小组（埃及）的专门知识这项工作将由埃及国家研究中心（应用有机化学系和聚合物颜料系）和明尼苏达大学化学系的两个研究小组合作进行&。 该计划允许在美国培训年轻的埃及科学家，也将使美国研究生和本科生受益。该计划将通过特定的UMN项目吸引少数民族学生参加暑期研究项目。该项目的结果将用于临床诊断，生物医学，工业和环境应用的高质量传感器。

This project supported by the Office of International Science and Engineering is through the U.S.-Egypt Joint Science and Technology fund and coevaluated through the NSF by the Analytical and Surface Chemistry Program. The project is conducted on the US side by Philippe Buhlmann & Andreas Stein of the University of Minnesota-Twin Cities, and develops solid-contacted potentiometric sensors that overcome instability and drift shortcomings of conventional electrodes by using 3-D ordered macroporous carbon as an electrode material infused with an ionophore-doped polymeric phase to achieve selectivity. The project takes advantage of the unique qualifications of the 4 participating groups, i.e., the expertise of the Abbas group (Egypt) with potentiometric sensors, and the Stein group expertise in the use of ionophores covalently attached to polymers, the experience of the Buhlmann group to employ selective, fouling resistant fluorous phases in these carbon sensors, and the expertise of the Abdel Ghaffar group (Egypt) in polymer science.The proposed work will be executed in collaboration between two research groups from the National Research Centre, Egypt (Departments of Applied Org. Chem. and Polymers & Pigments) and the University of Minnesota Chemistry Dept. The program allows training of younger Egyptian scientists in the USA and will also benefit US graduate and undergraduate students. The program will attract students from minority groups to summer research programs through specific UMN programs. The results of the project will be useful for high quality sensors for clinical diagnostics, biomedical, industrial and environmental applications.
