Design, Synthesis and Characterization of Hybrid Stratified MOF-Plasmonic Nanoparticle Materials for Detection and Destruction of Chemical Agents
Abstract
Multi-Functional Plasmonic Nanomaterials for Personal Protection. This proposal addresses the need for technologies that can be used to detect and destroy chemical warfare agents (CWAs) and toxic industrial chemicals (TICs). Multifunctional hybrid materials have the potential to combine sensing and decontamination functions in a single material. We propose to develop and characterize multifunctional metal-organic frameworks (MOFs) having ‘stratified’ structure for selective sorption and transport of target analytes to an embedded plasmonic nanoparticle core. The ultimate goal is the development of stratified hybrid MOFs that will concentrate target CWAs and TICs near the plasmonic core, where they can be detected through surface enhanced spectroscopy, such as with a hand-held infrared spectrometer. The plasmonic core will also facilitate photo-assisted degradation of CWAs and TICs. In the proposed work, non-precious metal plasmonic nanoparticles will be developed and characterized. We will use a combination of synthesis, analysis, and rigorous modeling to explore the fundamental properties of hybrid multifunctional materials consisting of stratified MOFs with plasmonic nanoparticle cores. This study will produce detailed understanding of the mechanisms for selective adsorption and transport of target analytes through stratified MOFs and of the plasmonic properties of non-precious metal nanoparticles embedded at the core. The knowledge gained through this research will facilitate the development of materials for both extremely sensitive detection and light-mediated destruction of chemical threats
