Sensitive Chemical Sensor To Detect A Broad Range Of Nitrogen-Based Explosives

Technology Benefits

Sensitve Rapid Low cost Versatile synthetic approach Single polymer Detects wide range of trace explosives Detects explosives on a variety of surfaces

Technology Application

Counter terrorism Forensic (e.g. examination of post blast residue) Screening baggage, personnel, or cargo Facility protection

Detailed Technology Description

This technology describes the synthesis of a polymer and a method for detecting a broad range of nitrogen-based explosives including nitraromatic based, nitramine based and nitrate ester-based high explosives. The polymer is excited at an appropriate range using a UV-B, UV-C, black light, LED or other illumination source. If an explosive has bound the polymer, then the polymer fluorescence will be quenched.
