  • Publication number: 20090281442
    Abstract: Aerosol collectors 10, 120 include pre-collection filters 100, 126, aerosol collection chambers 30, 130, and other exhaled breath conditioning and control features for providing not only accurate and efficient, but also reliable and reproducible aerosol collections that can be used in standardizations and can be compared in meaningful ways to other exhaled breath aerosol collections from the same test subject and from different test subjects. The aerosol collector 10 example includes electrostatic collection components 34, 40, and the aerosol collector 120 includes nucleating condensation components 168, 172 and vortex collection components 132, 138. Both include analyte extraction apparatus 50, 124.
    Type: Application

  • Publication number: 20050048599
    Abstract: The present invention relates to moving microorganisms to a surface, where they are grown in the presence and absence of antimicrobials, and by monitoring the growth of the microorganisms over time in the two conditions, their susceptibility to the antimicrobials can be determined. The microorganisms can be moved to the surface through electrophoresis, centrifugation or filtration. When the movement involves electrophoresis, the presence of oxidizing and reducing reagents lowers the voltage at which electrophoretic force can be generated and allows a broader range of means by which the target can be detected. Monitoring can comprise optical detection, and most conveniently includes the detection of individual microorganisms. The microorganisms can be stained in order to give information about their response to antimicrobials.
