Abstract: A filtration device including a contoured support having 1) an interior surface, 2) an outside peripheral surface spaced farther from a center of the contoured support than the interior surface, and 3) a rim enclosed and sealed to a perimeter of the contoured support. The filtration device includes macroscopic openings in the contoured support extending from the interior surface to the outside peripheral surface, and a plurality of nanofibers having diameters less than 1 micron. The nanofibers are disposed on the outside peripheral surface of the contoured support, and cover the macroscopic openings to form a filtration medium on the contoured support.

Abstract: 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.

Abstract: A filtration device including a base filtration material having openings for fluid flow there through and a filtration medium. The filtration medium includes a plurality of patterned nanofibers formed on the base filtration material. The filtration medium has a figure of merit greater than 30 kPa−1, where the figure of merit is given by −Log (Pt)/ΔP, where Pt is the fractional penetration of a specific aerosol particle diameter and ΔP is a pressure drop across the filtration medium corresponding to a face velocity of 5.3 cm/s and particle size of 0.3 microns.
