Abstract

Official abstract text for this publication.

This invention relates generally to characterizing bioaerosols and, more particularly, to a system for recovering, quantifying, identifying, and assessing the metabolic activities of bioaerosols based on their major biopolymer profiles (lipids, carbohydrate and protein) and more specific their genetic materials (DNA/RNA), such as airborne viruses, bacteria, fungi and pollens.

First claim

Opening claim text (preview).

1 - 19 . (canceled) 20 . A method of sampling, recovering and stabilizing bioaerosol materials comprising; a) providing; i) a condensation growth tube; and ii) an aerosol stream comprising water vapor and bioaerosol materials; b) directing said aerosol stream into said tube under said conditions that said vapor absorbs, adsorbs and/or condenses on said bioaerosol particles so as to form microdroplets; and c) collecting individual and/or a conglomerate of microdroplets into individual, sterile DNA-free containers containing a genomic, transcriptomic or proteomic preservative, wherein said microdroplets are simultaneously exposed to said preservative as they are collected. 21 . The method of claim 20 , wherein simultaneous preservation and capture occurs in the condensation growth tube. 22 . The method of claim 20 , wherein the method further comprises step d) recovery of bioaerosol particles as they exist in the air. 23 . The method of claim 22 , wherein said bioaerosol particles comprise microbial nucleic acids. 24 . The method of claim 20 , wherein preservation of said bioaerosol particles is quantitative. 25 . The method of claim 20 , wherein said condensation growth tube is RNA-free and DNA-free prior to use.
