  • COMBINATION TREPONEMAL AND NON-TREPONEMAL SYPHILIS TEST
    Publication number: 20170370931
    Abstract: Provided herein are multiplex assays for detecting antibodies indicative of presence and stage of syphilis infection in an individual. Individuals infected with syphilis produce antibodies directed to syphilis components and the lipid cellular debris associated with the infection. The present disclosure represents the first combination of these diverse antibody targets in a single assay.

  • Label-Free Multiplexing Bioassays Using Fluorescent Conjugated Polymers and Barcoded Nanoparticles
    Publication number: 20130065780
    Abstract: Label-free, multiplexed DNA assay using fluorescent conjugated polymers as a detection probe to illustrate hybridization on metallic striped nanorods are disclosed. Different DNA capture probes are encoded by the different reflectivity of Au and Ag stripe patterns. The integration of fluorescent conjugated polymers as detection moieties with metallic striped nanorods for multiplexed detection of clinically important cancer marker proteins in an immunoassay format is also provided.
