Paper Abstract

Using silicon based microfabrication and materials we have developed a photonic platform capable of single bioparticle analysis. This platform combines liquid and hollow core waveguides on the micron-scale (5 μm x 12 μm) to isolate femtoliter sized sample volumes. Fluorescence excitation and signals in the visible range are directed into and out of the sample volume at an orthogonal angle to maximize signal-to-noise. This paper reveals the development path of these structures over several device generations including innovations in material, geometries, and fabrication techniques to increase detection sensitivity.
