Impedimetric Sensor for Detection of ?9 -Tetrahydrocannabinol (THC)

Although cannabis was legalized in Canada for recreational use in October 2018, there remains no effective method to determine roadside cannabis impairment. The state of the art device for detecting cannabis use roadside is saliva-based which has several flaws, including the fact that THC remains in saliva up to 72 hours after intake. In this project, a sensor will be developed to detect THC in breath, where the compound is present only up to 5 hours after consumption. The intern will research the effect of electrode geometry and fabrication process on the sensitivity of the device, and complete device repeatability tests. This knowledge will be critical for SannTek’s development of an effective device. The device will be marketed to law enforcement officials for roadside testing and employers for workplace testing, providing tangible public safety benefits to all Canadians.
