1. An analytical device, comprising:

  • a substrate comprising a first surface and an array of optical waveguide cores proximal to the first surface;

    a plurality of optically resolvable molecular complexes, each of which is immobilized sufficiently proximal to the first surface to be illuminated by an evanescent field emanating from at least one of the optical waveguide cores when light is passed through said array; and

    at least a first excitation radiation source optically coupled to the array to provide the evanescent field by passing excitation light into the array.
