Abstract
The application of optical fibers as biosensors is a topic of increasing interest and importance. The evanescent wave technique with its short interaction distance is ideally suited to the measurement of biomolecules closely attached to the surface of a fiber.1 The use of a fluorescent tag attached to either antibody or antigen analytes thereby allows a quantitative measure of concentration from the fluorescence emanating from the fiber.2
