Abstract: A system for real-time detection of airborne pathogens is disclosed. The system includes: an air intake unit defining an inlet and an air inflow channel; a fan configured to cause air in a sampling environment to flow into the air inflow channel via the inlet; a cooling unit for cooling air in the air inflow channel; a collection chamber for collecting liquid water condensed from air in the air inflow channel, the collection chamber including: an active target substrate having a surface that is coated with bioreceptors; and a reference target substrate that is not coated with bioreceptors, and an optical detection unit that is configured to independently illuminate the active target substrate and the reference target substrate with light for detecting presence of an airborne pathogen.

Abstract: An air sampling system is disclosed. The air sampling system includes: an air inflow channel having an air inlet portion at a top end, the air inflow channel being oriented substantially vertically; a fan configured to cause air in a sampling environment to flow into the air inflow channel via the inlet portion; a cooling unit for cooling air in the air inflow channel, the cooling unit disposed downstream of the inlet portion; a collection chamber for collecting liquid water condensed from air in the air inflow channel, the collection chamber being fluidly connected to the air inflow channel; and a sensing unit for determining a volume of liquid in the collection chamber, wherein the cooling unit is controlled in response to signals generated by the sensing unit.
