A patent for a device to detect trace quantities of gases has been granted to a pair of Arkansas State University researchers.
Susan Davis Allen, director of the Arkansas Center for Laser Applications and Science and distinguished professor, and Scott Reeve, senior scientist with ACLAS and chemistry professor, were awarded the patent in August. It’s for a device called a “multi-color cavity ringdown-based detection.”
Its inventors say the device could have many applications. For example, it could detect the level of formaldehyde in homes or trailers, the level of alcohol in a person’s breath, or biomarkers indicating the likelihood of developing cancer.
Reeve said the tool sort of acts like a super-sensitive nose, detecting minute particles in the air.
