 The PAQ monitor is a novel device designed to detect SARS-CoV-2 virus particles in the air. It combines a high-flow wet cyclone air sampler with a nanobody-based ultra-sensitive micro-enuno-electrode biosensor. The device was tested in laboratory conditions and demonstrated a sensitivity of 77 to 83%, and a limit of detection of 7 to 35 viral RNA copies M3 of air. This technology could be used to quickly identify and track the spread of SARS-CoV-2 in indoor environments, allowing public health officials to implement rapid disease control measures.
