One way to halt the ongoing pandemic is a test that gives results in seconds. It’d accurately tell if someone is infected with the virus that causes COVID-19.
Currently, most tests use a deep nasal swab to obtain fluid. The tester transfers the sample to a laboratory. That has a machine for processing. It displays its results many hours or even days later.
Other lab machines display results in five minute. But those still require an expensive testing machine at each testing site.
Why Wait? New Device Detects COVID-19 in Seconds: technology
Now, researchers at Ohio State University have developed a new breathalyzer. It detects a COVID-19 infection within fifteen seconds. Results don’t require any interpretation. Anyone can use it.
This technology can screen many at once, such as:
– shoppers at markets,
– fans attending public events, as well as
– travelers at airports.
Perena Gouma, the lead developer, already had a sensor of nitric oxide and volatile organic compounds in breath. Those two gases announce the onset of an infectious disease.
Along with nitric oxide, COVID-19 spews two other metabolites. The new breathalyzer screens them all. The device may also monitor disease progression.
Why Wait? New Device Detects COVID-19 in Seconds: development
The medical field does not yet use breath analysis. Development is still in an early stage, beginning twenty years ago. The technology evolved from sensors used to detect gases in automobile exhaust.
Gouma’s team built their original breathalyzer in 2017. That one detected the onset of influenza before symptoms were evident. The new device incorporates nanomaterials that trap and measure gases.
Gouma is testing his new hand-held monitor. He aims to make it cheap to manufacture. That way he can distribute thousands of them widely, to every place people gather.
Imagine this detector in widespread use. People who need affordable, professional medical care could travel again. If you need to travel before then, contact DocTours to arrange everything.
