Emerging Infectious Disease Diagnostic via Novel Optoelectronic Halo Effect
Abstract
Forward deployed military units have a critical need for a robust, low cost, easy to use diagnostic system providing realtime, quantitative, and multiplex capability of identifying biomarkers for infectious disease, including tuberculosis. This is a project to develop a new diagnostic device for detection of the tuberculosis biomarker lipoarabinomannan based on a novel "plasmonic halo" effect. In the initial stage, various halo nanodevices using a set of chosen metals and dielectrics were fabricated, and their plasmonicoptical response / sensitivity characterized. A major finding was that bullseye halos are significantly more responsive than standard devices, with sensitivities above 100 nm/RIU (refractive index unit). Moreover, incorporation of inorganic quantum dots has shown promise for enhancing sensitivity further.
