Patent ID: 8274040

Claim:
An analytic device, comprising: a substrate comprising (a) at least one optical waveguide; (b) at least one nanometer-scale aperture that penetrates into a first side of the substrate and extends toward a core of the optical waveguide such that an analyte disposed therein is sufficiently proximal to the core to be illuminated by an evanescent field emanating from the core when optical energy is passed through the optical waveguide; (c) and at least one microlens array positioned between the optical waveguide and a second side of the substrate that is opposite the first side of the substrate, wherein a microlens within the microlens array directs photons emitted from the one nanometer-scale aperture toward the second side of the substrate; and a detector disposed proximal to the second side of the substrate to receive photons directed from the one nanometer-scale aperture.
