Invention Summary

bottles

This NDSU-developed invention is a dual-use technology that was initially reported under the spin electronics program funded by Department of Defense. The "spintronics" polymer is being tested for use in applications such as increased electronic or computer memory. However, this same material was also used by NDSU in sensor tests. The material provides an optical alert when it comes in contact with metallic poison such as insecticides that are in the same family as nerve gas and neurotoxins.

Benefits

  • GREEN TECHNOLOGY! Detects hazardous substances harmful to the environment, including neurotoxins, dangerous metals, organic poisons, pesticides, and some bio-toxins.
  • Reliably reports the presence of poison and toxins by visual and electronic signals
  • Enhances current field sensing operation with added portability, simplicity, and sensitivity
  • Immediate commercial applications in the areas of security operations, industrial safety, personal safety, health care, food processing, and food packaging

Invention Premise

When the detection compound of the invention comes in contact with the substance to be detected, the detection compound reacts with the substance, thereby changing its fluorescence properties. Because of this change in fluorescence, the detection compound can be used in a variety of sensors, including optical electrical sensors, bio-sensors, and surface acoustic wave sensors for the detection of various organophosphates and other hazardous materials.

Patents

This technology is patented with fully preserved US patent rights (issued US patents 7,700,040 7,897,402, and 7,910,058), and is available for licensing/partnering opportunities.
