Abstract
Official abstract text for this publication.
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 spectroscopy, thus detecting a possible variation indicative of one or more analytes, wherein the solvent is a deep eutectic solvents consisting of a mixture of ethylene glycol and choline chloride.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method of detection, comprising: contacting a soil or a surface with a filter paper wetted with a solvent, then subjecting the filter paper to spectroscopy and detecting any change in optical properties indicative of the presence of one or more analytes, wherein the solvent is the deep eutectic solvent consisting of a mixture of ethylene glycol and choline chloride. 2 . The method of claim 1 , wherein said one or more analytes includes an explosive. 3 . The method of claim 1 , wherein said one or more analytes includes a drug, nerve agent, biothreat, pesticide, or industrial pollutant. 4 . The method of claim 1 , further comprising allowing migration of at least one of said one or more analytes across said filter paper prior to said subjecting to spectroscopy. 5 . The method of claim 1 , wherein said spectroscopy is Fourier transform infrared spectroscopy or Raman spectroscopy. 6 . The method of claim 1 , wherein said contacting is performed by an unmanned aerial vehicle.
