MARYBEL RODRIGUEZ: More now, on the pandemic. French researchers are developing a new rapid COVID-19 test that connects to a smartphone to reveal results at home. CBS4's Ian Lee, shows us how it works.

IAN LEE: Ever since the pandemic began, researchers in France have been working on a way to test for COVID-19 quickly and accurately.

SABINE SZUNERITS: So since March, we try to develop a portable device, which everybody can use at home.

IAN LEE: The research at this French University started oddly enough with camels, llamas, and alpacas. Scientists took tiny antibody particles from the animals called, nanobodies. After some complicated science, they produced a device that plugs into a smartphone. A nasal or saliva swab is placed onto a strip. And if nanobodies come into contact with the virus, the test will know it.

SABINE SZUNERITS: And you start your mobile phone and the signal will occur. And depending on the height of the signal, you can say if you're COVID positive and negative.

IAN LEE: Researchers say initial trials of 300 samples were 90% accurate and delivered in 10 minutes.


IAN LEE: Creators of the CorDial-1 test say, "If it receives approval, it'll be cheap once manufacturing begins on a large scale." Ultimately, putting another weapon in the arsenal against the virus. Ian Lee, CBS News.

MARYBEL RODRIGUEZ: And the next phase of the project is to run a three month trial on more than 1,000 people.
