A waveguide sensor capable of direct, real-time detection and monitoring of analytes in the vicinity of the waveguide surface without requiring the tagging or labeling of the analyte, is described. Analytic and numerical calculations have predicted that by locally detecting either changes in the evanescent field or changes in the light coupled out of the waveguide as a result of the presence of the analyte, high detection sensitivity will be able to be achieved.
