UC San Diego is a developing sticker that works as a simple COVID-19 test on a mask.


San Digo (KABC) – UC San Diego researchers are developing a simpler method for testing COVID-19 risk. The technique comes as a sticker outside your mask.

“It can have a very profound impact on the trajectory of the epidemic,” said Jessie Joker, an associate professor at UC San Diego.

This device can be helpful if you are receiving treatment at home with COVID.

The test looks for the presence of a specific COVID-19 protease in people’s breath. As a person wears a mask throughout the day, he collects the drops.

Joker said, “At the end of the day, you click on a small blister pack, and if it changes color, it means that you are exposed to COVID and you should do some additional testing.”

The test uses a technique called “Colorimetric Detection”, which is similar to home-pregnancy test indicators.

Jokerst compares it to a smoke alarm. The test will not tell you exactly what is going on, but it serves as a warning that you need to take further action for safety.
Joker explained, “This is what we were trying to develop. It could be a tool that could say, ‘Hey, there’s an elevated risk today, and everyone should do some additional testing.”

Such color-based testing has never been used for viral detection.

The Joker says that once the epidemic is over, these tests can still assess the risk of diseases such as SARS and MERS.
