  • Unmanned aerial vehicle system for the extraction and electrochemical detection of explosives and explosive components in soils using filter paper and electrolyte
    Patent number: 9857293
    Abstract: Described herein is an approach using inexpensive, disposable chemical sensor probes that can be mounted on a small unmanned aerial vehicles (UAVs) and used to analyze a site (such as one known or suspected to contain explosive residue, spilled material or contaminated soil) without the need for a person to conduct ground operations at the site. The method involves contacting a soil or a surface with a filter paper wetted with a solvent, then subjecting the filter paper to voltammetry and/or spectroscopy, thus detecting a possible variation indicative of one or more analytes, wherein the solvent is the deep eutectic solvent consisting of a mixture of ethylene glycol and choline chloride.
    Type: Grant
    Filed: November 18, 2016
    Date of Patent: January 2, 2018
    Assignee: The United States of America, as represented by the Secretary of the Navy
    Inventors: Daniel Zabetakis, Scott A. Trammell, Walter J. Dressick, David A. Stenger, Jasenka Verbarg

  • Method for the extraction and electrochemical detection of explosives and explosive components in soils using electrodes, filter paper, and electrolyte
    Patent number: 9557296
    Abstract: Described herein is an approach using inexpensive, disposable chemical sensor probes that can be mounted on a small unmanned aerial vehicles (UAVs) and used to analyze a site (such as one known or suspected to contain explosive residue, spilled material or contaminated soil) without the need for a person to conduct ground operations at the site. The method involves contacting a soil or a surface with a filter paper wetted with a solvent, then subjecting the filter paper to voltammetry and/or spectroscopy, thus detecting a possible variation indicative of one or more analytes, wherein the solvent is selected from the group consisting of polar aprotic or protic solvents having a boiling point of at least 100° C., room temperature ionic liquids, and deep eutectic solvents.
