Capillary-channeled Polymer Fibers as Support Media for Various Spectroscopic Probes

Market Overview:

There is current need for low-cost diagnostic devices with high sensitivity which enable specific analysis of minimal volumes of fluid for the application of low-cost point-of-use diagnostics for clinical, laboratory, or at-home use. This technology features the application of channeled 4DG fibers for diagnostic and laboratory applications.  4DG fibers are part of a patent portfolio donated to Clemson University by Eastman Chemical which exhibit superior fluid-wicking properties.  These fiber probes can be functionalized and coated for high specificity and high sensitivity interactions for laboratory and clinical testing and can be analyzed directly using fluorescence or colorimetric indicators.
