Need a quick breath check before your big meeting or your big date?

Well, scientists from South Korea may be able to help.

They've engineered a portable device that detects even the tiniest trace of hydrogen sulfide.

The stuff that smells like rotten eggs and is one of the primary offenders in oral obnoxiousness. Their work appears in the journal Analytical Chemistry.

Bad breath, aka halitosis, can be more than a social inconvenience. A skunky mouth also may point

The only diagnosis is very significant to prolong your healthy life.

Juni Cha of the Korea Advanced Institute of Science and Technology.

He says that most of the instruments used for diagnostics are found in clinics or hospitals,

which may be tough to get to.

And the electronic sensors that are currently used to sniff

out various gases require a power source and precise calibration. Not easy when you're out

and about. So we came up with a strategy to develop color metric gas sensors, which changes

color when detecting biomarker gases. Think of it as a litmus test for your exhalation.
