1. A method of detecting a signal from an analyte, comprising:
- providing a substrate comprising a first surface and at least a first optical waveguide disposed upon the first surface;
providing an individual analyte disposed sufficiently proximal to the first surface and external to the waveguide to be illuminated by an evanescent field emanating from the waveguide when light is passed through the waveguide, wherein the individual analyte is immobilized on the first surface such that a signal from the individual analyte is optically resolvable from any other signal from any other analyte immobilized on the first surface and illuminated by the evanescent field;
directing light through the first waveguide such that the evanescent field from the waveguide illuminates the individual analyte; and
detecting a signal from the individual analyte.

Abstract
Substrates, systems and methods for analyzing materials that include waveguide arrays disposed upon or within the substrate such that evanescent fields emanating from the waveguides illuminate materials disposed upon or proximal to the surface of the substrate, permitting analysis of such materials. The substrates, systems and methods are used in a variety of analytical operations, including, inter alia, nucleic acid analysis, including hybridization and sequencing analyses, cellular analyses and other molecular analyses.

15. A method of detecting a signal from an individual analyte, comprising:
-
providing a substrate comprising a first surface and at least a first optical waveguide disposed upon the first surface, wherein the substrate has a refractive index that is lower than that of the first optical waveguide and further wherein the first optical waveguide extends into and is at least partially enclosed by the substrate; providing an individual analyte disposed sufficiently proximal to the first surface and external to the waveguide to be illuminated by an evanescent field emanating from the waveguide when light is passed through the waveguide, wherein the individual analyte is immobilized on the first surface such that a signal from the individual analyte is optically resolvable from any other signal from any other analyte immobilized on the first surface and illuminated by the evanescent field; directing light through the first waveguide such that the evanescent field from the waveguide illuminates the individual analyte; and detecting a signal from the individual analyte.
