  • Patent number: 9357946
    Abstract: The present invention provides a direct sampler and detector for analytes found in exhaled breath condensate. Analytes in the breath condensate are detected instantaneously as they condense prior to reaching the sensor surface or condense directly on the sensor surface. Because the analysis or assay is performed immediately after patient exhalation, analyte stability is significantly improved providing accurate, reliable, consistent, and clinically applicable results. In certain embodiments, combined breath condensate/breath samplers and detectors are provided, enabling multiplexed analysis of condensed and vapor-phase analytes provided in a single sampling session. Breath is collected and directed to one or more subsystems. Within each subsystem, the breath portion is either condensed or prevented from condensing.

  • Patent number: 8993346
    Abstract: Provided herein is a new hybrid material system, mCNT, including magnetic carbon nanotubes for biological and medical sensing applications. In certain embodiments, the systems include magnetic material on the interior of carbon nanotubes (CNTs). The amount of magnetic particles inside CNTs may be such that mCNT can respond to small, low cost, portable magnet. The exterior CNT surface is kept intact for biomolecular attachments or other functionalizations. Performance enhancement with this novel material includes improved sensitivity, reduced response time, and reduced sample volume. According to various embodiments, the mCNTs are substrates for the adherence of molecules participating in these assays or as active sensing elements. Also provided are methods of fabricating two-dimensional mCNT and CNT networks on printed electrodes.

  • Publication number: 20070020671
    Abstract: Methods for querying biological samples to detect genetic mutations, particularly insertions and deletions, by co-amplification of a gene of interest in conjunction with a paralogous gene. When the gene of interest and the corresponding paralogous gene are selected from the CYP450 family, the resulting ratios may predict how a particular patient metabolizes certain prescription drugs.

  • Patent number: 7135283
    Abstract: Novel polymorphisms of prokaryotic topoisomerase type II Gyr A, Gyr B and parC gene loci are provided. These polymorphisms differentiate very closely related organisms and provide a means to identify pathogenicity and drug resistance. For example, drug resistance such as resistance to methicillin, a drug which is not metabolically tied to topoisomerase function, may be determined by polymorphisms in the Gyrase A locus. Identification of such drug resistance by such unrelated loci is indicative of heretofore unrecognized [sub]species of Staphylococcus aureus.
