1. An analytical device, comprising:

  • a substrate comprising a first surface and at least a first optical waveguide disposed upon the first surface;

    an optically resolvable molecular complex immobilized within a confined region and sufficiently proximal to the first surface to be illuminated by an evanescent field emanating from the optical waveguide when light is passed through said optical waveguide; and

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