Abstract

A target molecule at a binding site is detected using an optical waveguide having a surface proximate to the binding site, and a waveguide detector coupled to the optical waveguide. An incident light beam is applied to the binding site along an axis transverse to the surface of the optical waveguide. The incident light beam impinges an optical indicator associated with the target molecule to form secondary light which is coupled into the optical waveguide. The secondary light is detected by the waveguide detector to thereby detect the target molecule.
