Graphenated polyaniline nanosensor system for real time determination of chemical warfare agents
Introduction:The chemical warfare agents (CWA) such as 3-quinuclidinyl benzilate (QNB, BZ), 2, 2-Diphenyl-2-hydroxyacetic acid and Quinuclidin-3-ol are among anticholinergic agents that affects both the peripheral and central nervous systems (CNS). 3-quinuclidinyl benzilate (QNB, BZ) is the most potent anticholinergic psychomimetics known, with only small doses necessary to produce incapacitation which impairs the performance of an enemy by targeting the central nervous system while others are used as precursors. Several classical methods such as high performance liquid chromatography (HPLC) and gas chromatography (GC) has been developed for their determination. However, these methods are known to manifest underlying disadvantages such as complicated pre-treatment, high costs and time consuming processes. .Herein a simple, less time consuming electrochemical method in the rim of an electrochemical sensor (Graphenated SensorTek) is being proposed for real time and low cost determination of CWA. The sensor system will be based on the use of graphenated polyaniline nanosensor systems doped with transition metal oxides Aim/objectiveThe main aim of this study is to develop a novel method for harnessing the properties of electro conductive polymers in sensor technology by using polymeric nanotubes blends in the preparation of high performance sensor devices,The objectives include:To produce novel graphenated polymers doped with transition metal oxides for the production of ultrasensitive CWA sensor systemsMethodologyElectrically conducting graphenated PANI nanomaterial will be electrochemically prepared by in situ oxidative polymerization of the monomer in acid solutions using transition metal oxides (ZnO) as dopants.Expected resultA nanosensor device containing intrinsically polymer that have been graphenated and doped with transition metal that will be applicable for real time determination of CWA.Success in this will have impact for the development and promotion of scientific and technical knowledge in the field of chemistry for research, environmental and other peaceful purposes.
