Breath Monitor Can Easily Detect Health Problems

Researchers at Stony Brook University have recently developed a new nanomedicine device that can instantly detect and monitor diseases by simply exhaling onto it. Led by chief researcher Perena Gouma, the project titled Nanosensor Device for Breath Acetone Detection introduced a single breath analysis diagnostic tool for monitoring disease or metabolic functions that can be used to check cholesterol levels, diabetes, and even lung cancer. among many others.

From the press release:

The ability to easily capture gases that detect disease early will empower individuals to take control of their own health. And it will simplify the process of monitoring diseases like diabetes. Presently, blood is required to monitor diabetes, but this new process will enable individuals to test themselves by simply breathing once into the device.

There are over 300 compounds in the breath, some of which are established indicators of disease.  The only way to be able to use these indicators is with very selective sensors for a particular gas.  “That’s where the breakthrough in the technology has been,” explains Gouma. “We have been able to make low-cost sensors that mark one particular gas or one particular family of gases and discriminate against another.”

In order to detect a particular disease, the specific sensors need to be identified. “For instance, if nitric oxide is important to asthma, we can detect nitric oxide.  If acetone is important to diabetes, we can detect acetone,” notes Gouma. “It’s beyond the alcohol breath analyzer that people are familiar with that is non-selective.”
