Abstract : This report describes the fabrication and use of capture matrices for the enhanced detection of harmful chemicals. Capture matrices are composed of affinity ligands grafted onto magnetic microparticles. These capture matrices are essentially preconcentrators/transducers that can be used with either field-deployable sensors or microelectromechanical systems (MEMS) devices. For MEMS, these capture matrices address integrating the device with real-world sampling. Depending on the chemical nature of the affinity ligands, capture matrices can be used to enhance the detection of toxic industrial chemicals (TICs), explosive materials, and chemical warfare agents. The technology developed has relevancy in information dominance. Capture matrices, when used with either MEMs or current field-deployable detectors, will provide the warfighter with information on what chemical species are present in the environment. This will provide the warfighter with enhanced situational awareness and understanding as well as force protection. This technology can also be used for long-term monitoring (LTM) of contaminated U.S. Navy and Department of Defense (DoD) sites. More than 2000 DoD sites have undergone remediation. Long-term monitoring of these sites is required. This LTM cannot be deferred and is a significant part of remediation life-cycle costs for the DoD. The capture matrices technology will benefit the fleet by reducing the costs of LTM. The savings can then be used to procure equipment, vessels, etc. that will directly benefit the warfighter.
