Instantly Preserve Genetic Information of Bioaerosols with Gentle Condensation Capture

Dr. Hernandez at the University of Colorado Boulder, along with Aerosol Devices, developed a new method for the collection of bioaerosols directly into a genomic preservative media or onto pre-treated solid substrates (patent pending).  Instant genomic preservation using condensation capture provides samples that are immediately compatible with modern forensic biology assays – most notably DNA and RNA sequencing.  Conventional aerosol sampling methods use filters or impactors, which impart intense mechanical stresses that damage airborne microbes.  Many bioaerosol protocols also employ standard culturing; however, we now know from genetic surveys, that a vast majority of environmental microorganisms cannot be recovered by culturing1.  Preserving the microbe’s physiology provides for more confident microbial identification, as well as the potential for determining the metabolic status of airborne microbes, regardless of culturability.
