Abstract:
1. An array for optical analysis comprising: a transparent substrate having an upper surface comprising an array of at least 10,000 features comprising truncated cones having tops with diameters between about 0.5 microns and about 5 microns extending above the surface of the substrate, each feature having a top and sides, wherein the sides of the features comprise a reflective coating, wherein, on top of the transparent layer, and extending between the features, is a planarization layer, the planarization layer disposed such that the top of the planarization layer and the tops of the features are in the same plane, wherein, extending across the top of the planarization layer and tops of features is a cladding layer; wherein the top of each of feature comprises a nanoscale aperture in the cladding layer, wherein light emitted down into the transparent layer from the nanoscale apertures is re-directed by the reflective coating on the sides of the array of features.
