Optical fiber biochemical sensors for continuous monitoring

As the market for biosensors continues to grow, scientists are striving to fill the need for sensors for monitoring specific biochemicals. Receptor-based optical sensors show some promising advantages over other sensor types, particularly for use in vivo. Until now, these sensors have been too costly to produce for the commercial market. This article describes the various sensors that have been developed and detection methods that use optical fibers, as well as a proposed new configuration for a reversible optical biosensor.
