"Real-time surveillance of airborne SARS-CoV-2 virus is a technological gap
that has eluded the scientific community since the beginning of the COVID-19
pandemic. Offline air sampling techniques for SARS-CoV-2 detection suffer from
longer turnaround times and require skilled labor. Here, we present a
proof-of-concept pathogen Air Quality (pAQ) monitor for real-time (5 min time
resolution) direct detection of SARS-CoV-2 aerosols. The system synergistically
integrates a high flow (~1000 lpm) wet cyclone air sampler and a nanobody-based
ultrasensitive micro-immunoelectrode biosensor. The wet cyclone showed
comparable or better virus sampling performance than commercially available
samplers. Laboratory experiments demonstrate a device sensitivity of 77–83% and
a limit of detection of 7-35 viral RNA copies/m^3 of air. Our pAQ monitor is
suited for point-of-need surveillance of SARS-CoV-2 variants in indoor
environments and can be adapted for multiplexed detection of other respiratory
pathogens of interest. Widespread adoption of such technology could assist
public health officials with implementing rapid disease control measures."
