摘要： The present disclosure describes a single-use microfluidic cartridge that is can be utilized with a portable and handheld breath collection and analysis device to detect a presence of a target chemical in human breath. The cartridge receives an air sample of human breath, processes it to extract the target chemical in solution, and reacts the solution with chemical reagent(s) to determine a concentration level of the target chemical present in the collected breath sample. Additionally, a portion of the collected sample can be contained in a separate reservoir of the cartridge of evidence preservation. The cartridge may further contain a cryptographic computing chip to store information regarding the sample processed within the cartridge.

摘要： The present disclosure describes systems, methods, and apparatus for a portable and handheld mechanical breath collection device. The mechanical breath collection device collects air from a human subject, filters out saliva from the human subject, and collects aerosolized droplets from the received air via inertial impaction on an impactor surface. A target chemical is then extracted from the collected aerosolized droplets, and analyzed. In this way, a concentration of a target chemical present from the human subject can be determined by the portable and handheld device.
