Integrated illumination of optical analytical devices
First Claim
1. An analytical device comprising:
- a substrate;
an integrated illumination element comprising a waveguide source;
a plurality of illumination volumes; and
a plurality of detector elements;
whereinthe integrated illumination element is disposed above the surface of the substrate;
the plurality of detector elements are disposed below the surface of the substrate;
the integrated illumination element is partly surrounded by an opaque layer; and
the plurality of illumination volumes are contained in a plurality of nanowells disposed above the surface of the substrate and in the same layer of the device as the integrated illumination element, wherein the nanowells are configured in a row adjacent to the integrated illumination element, wherein at least a first nanowell comprises a bottom surface and a first side surface, and wherein the first nanowell is optically coupled to the integrated illumination element through an opening in the opaque layer and to one of the detector elements.

Abstract
Optical analytical devices and their methods of use are provided. The devices are useful in the analysis of highly multiplexed optical reactions in large numbers at high densities, including biochemical reactions, such as nucleic acid sequencing reactions. The devices include integrated illumination elements and optical waveguides for illumination of the optical reactions. The devices further provide for the efficient coupling of optical excitation energy from the waveguides to the optical reactions. Optical signals emitted from the reactions can thus be measured with high sensitivity and discrimination using features such as spectra, amplitude, and time resolution, or combinations thereof. The devices of the invention are well suited for miniaturization and high throughput.
