Patent number: 10876145Abstract: 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.Type: GrantFiled: May 27, 2020Date of Patent: December 29, 2020Inventors: David S. Ensor, Howard Jerome Walls, Karin K. Foarde, Susanne Vera Hering, Steven Russel Spielman

Patent number: 10208331Abstract: A bioparticle collection device and an aerosol collection system. The bioparticle collection device includes a collection medium including a plurality of fibers formed into a fiber mat and configured to collect bioparticles thereon, and includes a viability enhancing material provider disposed in a vicinity of the plurality of fibers and configured to provide a viability enhancing material to the collected bioparticles to maintain viability of the bioparticles collected by the fiber mat. The aerosol collection system includes an aerosol pumping device configured to entrain particles in an gas stream, an aerosol saturation device configured to saturate the particles in the gas stream with a biocompatible liquid, and an aerosol collection medium downstream from the aerosol saturation device and including a plurality of fibers formed into a fiber mat for collection of the saturated aerosol particles.Type: GrantFiled: April 27, 2018Date of Patent: February 19, 2019Assignee: Research Triangle InstituteInventors: David Samuel Ensor, Howard Jerome Walls, Karin K.
