Description

Research Topic Description, including Problem Statement:

The goal of this research topic is to identify stand-off spectral changes to Genetically Modified Organism (GMO) and non-GMO agricultural crops as a result of a specific chemical uptake. The chemical classes to be considered include: organo-phosphates; thiol esters; carbamates; N, S, or F hetero-substituted organic bridged bicyclics; carbon nano-structures, and piperidinones.Both GMO and non-GMO plant species need to be considered independently, since the genetic differences could impact the metabolic pathway of intrusive chemicals, and thus provide different spectral results. One research area should focus on how to identify chemically induced spectroscopic changes to a plant. Consider the following questions to focus the research:

  • Which frequencies, or combination of frequencies, can be used to detect changes to a plant as a result of a chemical uptake?
  • What chemical concentrations need to be present for spectral changes to be noted?
  • How does the plant’s lifecycle impact the chemical uptake and related spectral changes (both age at point of uptake and latency effects)?

A second research area should focus on how to determine the fundamental mechanism by which a plant ingests and metabolizes the listed chemical classes. This will allow for a correlation between the collected spectral data and the plant's mechanism, and allow for data extrapolation to other chemicals of interest. Research in this area will allow for a means to measure crop health, define composition, and detect any insults from a stand-off position.

 

Example Approaches:

Approaches to this project could use a variety of techniques, but are in no way limited to:

  • Using single-, multi-, and/or broad-band spectroscopic techniques to measure in vivo changes to plant spectrums, due to a specific chemical exposure. Infrared (IR), near infrared (NIR), visible, and/or ultra-violet (UV) frequencies should be considered.
  • Using field scale spectral measurements, identify plants that have been impacted by an exposure to the listed chemical classes.
  • Using multi-element Nuclear Magnetic Resonance samples, mass spectrometry, as well as other analytical techniques, determine the metabolic pathway that the plants use to ingest the listed chemical classes. Additionally it would be of value to determine if any of the heteroatoms are retained in the plant's system.
  • Develop chemical modeling techniques to theorize possible mechanistic chemical uptake and metabolism methodologies.

 

Relevance to the Intelligence Community:

Identifying spectral changes to agricultural crops would provide a means to measure crop health, define composition, and detect any insults from a stand-off position. Determining mechanistic pathways would provide the fundamental information on potential susceptibilities to other undefined chemical threats. Finally, identifying spectral changes as a result of exposure to the listed chemical classes would provide a theoretical means to detect chemical emissions by a non-intrusive means.
