  • Self-indicating colorimetric response materials for removal and sensing of toxic chemicals and narcotics
    Patent number: 11402322
    Abstract: Processes, compositions, and sensors for sensing a variety of toxic chemicals based on colorimetric changes. Exemplary process for sensing a toxic chemical includes contacting a toxic chemical, or byproduct thereof, with a sorbent that includes a porous metal hydroxide or a porous mixed-metal oxide/hydroxide and a transition metal reactant suitable to react with a toxic chemical or byproduct thereof. The sorbent is contacted with the toxic chemical or byproduct thereof for a sampling time. A difference between a post-exposure colorimetric state of the sorbent and a pre-exposure colorimetric state of the sorbent is determined to thereby detect exposure to, or the presence of, the toxic chemical or byproduct thereof.
    Type: Grant
    Filed: July 29, 2020
    Date of Patent: August 2, 2022
    Assignee: The United States of America as Represented by the Secretary of the Army
    Inventors: Jennifer R Soliz, Darren K Emge, Ian J Pardoe, Gregory W Peterson
