Thermo Fisher Scientific Inc. Wednesday unveiled a device that collects samples of indoor air to test for pathogens, including the virus that causes Covid-19.
The device, called the AerosolSense Sampler, collects samples of ambient air and traps pathogens using a substrate. The samples can later be analyzed in a laboratory using polymerase chain reaction testing to test for SARS-CoV-2--the Covid-19 virus--or other pathogens.
Although the machine does not produce immediate results, it could help institutions confirm that the pathogen was present in a particular place and time, Thermo Fisher said. That information could help businesses, schools and other institutions make decisions about how to respond if people test positive for the disease or become symptomatic.
Thermo Fisher said that it expects individual testing would continue to be a foundational component of Covid-19 surveillance and public-health measures.
