“We asked ourselves, since this virus is just like a nano-particle or a quantum dot with a diameter between 100nm to 140nm in terms of its size and electrical properties, can we detect it using methods from the worlds of physics, photonics and electrical engineering?" says professor Gabby Sarusi at Ben-Gurion University to Australian Jewish News.
“We discovered that the answer is yes, this virus resonates in the THz frequency, and spectroscopy in these frequencies reveals it promptly.”
It is a hand-held device which contains a chip with sensors to capture tiny particles from the breath. The chip is then read through a THz spectroscopy, and within a minute they can tell if someone has the coronavirus.
This could have a significant effect on places where you need to test lots of people fast, like airports.
