A 3D-printed COVID-19 breath test delivers results within 60 seconds from just one or two breaths, according to Washington University in St. Louis researchers.It’s the same team that recently developed an air monitor that can detect the COVID-19-causing SARS-CoV-2 virus in the air within minutes.
Researchers from the McKelvey School of Engineering and the School of Medicine used the same ultrasensitive biosensing technique for the breath test.
The small, portable and adaptable device could help fight the airborne virus as at-home rapid tests increasingly report false negatives for new SARS-CoV-2 variants. Most COVID-19 transmission is still pre-symptomatic and asymptomatic.
The researchers envision their device being used for rapid diagnosis by doctors or to scr…
