Abstract
An aerosol collection system and method. The system includes a bio-aerosol delivery device configured to supply bioparticles in a gas stream, a moisture exchange device including a partition member coupled to the gas stream and configured to humidify or dehumidify the bioparticles in the gas stream, and an aerosol collection medium downstream from the moisture exchange device and configured to collect the bioparticles. The method includes delivering bioparticles in a gas stream, humidifying or dehumidifying the bioparticles in the gas stream by transport of water across a partition member and into a vapor phase of the gas stream, and collecting the bioparticles by a collection medium.
