    摘要： 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.

    摘要： 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. The technique also allows real-time continuous monitoring, thus allowing immediate feedback to both medical professionals and additional hardware such as ventilators, anesthesia machines, drug infusion systems and cardiac pacemakers.

    摘要： 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.
