Abstract
Systems, techniques and compositions can detect and measure a target substance, such as THC, in a constituent sample from exhaled human breath.
Claims3
A method of detecting THC in exhaled breath, comprising:
- receiving from a breath capture device an exhaled breath sample;
- processing the breath sample such that THC in the breath sample forms a fluorescent-labeled THC sample adduct dissolved in a nonpolar phase of an adduct solution;
- activating a fluorophore of the fluorescent-labeled THC sample adduct by adding a liquid phase chemical activator acryloyl species to the nonpolar phase;
- and
- detecting by determining an amount of THC in the breath sample based on the measured fluorescence of the activated fluorophore of the fluorescent-labeled THC sample adduct in the nonpolar phase isolated from aqueous media.
