That is about as sensitive as PCR nasal swab tests, says Rajan Chakrabarty, an aerosol scientist at Washington University in St. Louis. His team worked \u201cnonstop\u201d for three years to create the detector, he says. <\/p>\n\n\n\n<p>One of the main challenges when sampling airborne viruses is collecting enough air to concentrate viral particles at detectable levels. Previous attempts have sucked in between 2 and 8 cubic meters of air per minute. This detector pulls in 1,000 cubic meters of air each minute.<\/p>\n\n\n\n<p>To trap the virus, \u201cwe create an artificial cyclone inside of the sampler,\u201d Chakrabarty says, by swirling liquid at high speed. Viruses get trapped in the wall of the cyclone and concentrated for analysis. Any viruses not captured in the liquid get filtered out of the air with a HEPA filter attached to the device. After five minutes of collection, the liquid is pumped to a biosensor.<\/p>\n<\/div><\/div>","protected":false},"excerpt":{"rendered":"<p>Science News If you\u2019ve ever thought it would be great to walk into a room and know whether the virus that causes COVID-19 is hanging around, scientists have a device for you.
