This research project established the understanding necessary for the stacked planar affinity-regulated resonate optical waveguide (SPARROW) architecture to serve as a transducer device platform for rapid biomolecular detection. SPARROW structures have been grown with waveguide losses of less than 1 dB/cm. Thin biolayers of less than 10 nm were achieved and SAM attachment to polycrystalline surfaces studied. SPARROW transducer measurements were conducted using sucrose analyte solutions applied to the top ...
