Systems and techniques for detecting a target substance, such as THC, in a breath constituent sample are provided.

System and method for target substance identification

An ingestible device is disclosed which can produce spectral data of one or more analytes, as well as associated methods for characterizing the gastrointestinal tract of a subject which contains such analytes. Related kits and systems are also disclosed.

Ingestible device and associated methods

Systems, techniques and compositions can detect and measure a target substance, such as THC, in a constituent sample from exhaled human breath.

Detection and measurement of target substance in exhaled breath

Cartridge-based thermocyclers can include cartridges that are configured to move a fluid between distinct chambers. In some cases, the cartridge-based thermocyclers can be used for thermocycling a sample fluid comprising a deoxyribonucleic acid (DNA) target to perform polymerase chain reaction (PCR). Individual chambers can be heated, cooled, and/or compressed to mix fluid within the chamber or to propel fluid in the chamber into another chamber. The cartridges can have a laminate construction. The cartridges can be configured to enable multiplexed thermocycling and/or detection.

Cartridge-based thermocycler

Chemical compositions and methods provide labeling, detection and measurement of target substances in exhaled human breath, and can be implemented in connection with a handheld device&#x2014;much like a Breathalyzer portable breath testing unit for alcohol&#x2014;to support rapid quantification of levels of cannabinoid compounds, such as tetrahydrocannabinol (THC), of suspected users at the roadside.
