Biosensors for field analytical monitoring

The development of cost-effective on-site methods for environmental monitoring is instrumental to managing risks posed by environmental contamination. Biosensors show the potential to complement both laboratory-based and field analytical methods for environmental monitoring. Although a wide variety of biosensors have been reported for potential environmental applications, relatively few of these have progressed into commercial markets. Advances in screening methods for areas such as toxicity, bioavailability, and multiple analytes, as well as incorporation of these devices as detectors in chromatographic systems, could possibly widen the market and allow these techniques to be more competitive. © 1998 John Wiley & Sons, Inc.
