SUBSTRATES AND OPTICAL SYSTEMS AND METHODS OF USE THEREOF

Abstract:

This invention provides devices for use in various analytical applications including single-molecule analytical reactions. Methods for detecting analytes optically by propagating optical energy by waveguides within a substrate are provided. Analytical devices are provided which have both shallow and deep waveguides in which illumination light is transported through the deep waveguides and coupled into the shallow waveguides. The shallow waveguides provide evanescent field illumination to analytes, such as single-molecule analytes, within nanometer scale wells. Integrated devices including integrated detectors such as CMOS detectors are included.
