Paper Abstract

Planar optical waveguides may be used for the sensitive real-time interrogation of the optical properties of very thin films attached at surfaces, and microfabrication allows the definition of integrated optical circuits, including electrodes, for sensor arrays. Sensing techniques based upon thin-film absorption and refractive index changes are presented, including electrochemically-controlled surface reactions, and present work on fluoroimmunosensor arrays and instrumentation are discussed. In particular, integrated optical immunoprobes for environmental analysis are described.
