Carbon Nanotubes for Cannabis Control
Freeing the roads of THC-intoxicated drivers, one breathalyzer test at a time
Jonathan James | | Quick Read
There is no reliable method for verifying cannabis intoxication at the roadside; rather, confirmation must be achieved using laborious, lab-based LC-MS methods. A portable THC detector could, therefore, streamline law enforcement efforts and protect the public. To that end, Alexander Star and colleagues have developed a handheld breathalyzer that uses carbon nanotubes to detect THC in human breath (1).
The initial model was assembled using an off-the-shelf electronic prototyping platform and 3D printed shell in a matter of weeks. “We wanted the first iteration of the prototype to be as simple and mechanically robust as possible,” says Star. “To our great surprise – and delight – we quickly discovered that consumer-grade components were more than capable of meeting our needs.”
