Abstract
A method and composition of matter for detecting and decontaminating hazardous chemicals, the composition of matter including: a magnetic material for any of chemisorbing, molecularly dissociating, or decomposing a hazardous chemical, wherein the magnetic material changes its magnetic moment upon any of chemisorption, decomposition, and molecular dissociation of the hazardous chemical and the change in magnetic moment is used to detect the presence of the hazardous chemical, and wherein the hazardous chemical includes any of toxic industrial chemicals, chemical warfare agents, and chemical warfare agent related compounds.
Claims6
A device for detecting and decontaminating hazardous chemicals, comprising:
- a substrate supporting a magnetic material fabricated as a thin film on said substrate;
- a circuit board, wherein said substrate is placed on said circuit board;
- a rare-Earth magnet connected to said circuit board;
- an inductor capacitor (LC) circuit detector connected to said circuit board, wherein said LC circuit is configured to measure a change in a signal from said magnetic thin film upon any of chemisorption, decomposition, and molecular dissociation of a hazardous chemical, causing a change in magnetic moment in said magnetic material, and said change in signal is used to detect the presence of the hazardous chemical.
