Passive air sampler clip can help assess personal exposure to SARS-CoV-2, which could be helpful for workers in high-risk settings, like restaurants or health care facilities.
Novel passive air sampler clip can help assess personal exposure to SARS-CoV-2, which could be helpful for workers in high-risk settings, like restaurants or health care facilities, as per the report in ACS’ Environmental Science & Technology Letters. COVID-19 is transmitted through the inhalation of virus-laden aerosols, and respiratory droplets that infected individuals expel by coughing, sneezing, speaking, or breathing.
‘New wearable passive air sampler, called Fresh Air Clip, adsorbs virus-laden aerosols on a polydimethylsiloxane (PDMS) surface.’

Researchers have used active air sampling devices to detect airborne SARS-CoV-2 in indoor settings; however, these monitors are typically large, expensive, non-portable, and require electricity.Read More..
Krystal Pollitt and colleagues wanted to develop a small, lightweight, inexpensive, and wearable device that doesn’t require a power source to better understand personal exposures to the virus.
The researchers developed a wearable passive air sampler, the Fresh Air Clip, that continually adsorbs virus-laden aerosols on a polydimethylsiloxane (PDMS) surface.
The team tested the air sampler in a rotating drum in which they generated aerosols containing a surrogate virus, a bacteriophage with similar properties to SARS-CoV-2.
They detected a virus on the PDMS sampler using the polymerase chain reaction (PCR), showing that the device could be used to reliably estimate airborne virus concentrations.
