7. Outlook
At present, the food industry is not yet very receptive to biosensor technology. It is probably for the rapid detection of microorganisms or toxins that this type of technology has the best chance of developing, provided certain key problems are resolved. To compete with HPLC, capillary electrophoresis or other analytical techniques, biosensors need to be designed to measure several different analytes in parallel using a single analyzer, and without having to change any of the biosensor components. As Biacore systems are only capable of analyzing 4 to 8 analytes simultaneously, new systems have recently become available which can monitor a greater number of analytes in a single analysis. In particular, Applied Biosystems' 8500 Affinity Chip Analyzer platform [ http://www. appliedbiosystems.com/8500...

Outlook
Economic data
The biosensor industry is booming. The market comprises 4 segments: medical, environmental, agri-food and military, with medical applications accounting for the vast majority (90% of sales are of glucose-detecting biosensors).
In the food industry, pathogen detection is the biggest market. In the USA, a recent study

Commercially available biosensors
Despite a large number of publications on biosensors applied to food analysis, only a small number of systems are commercially available. The disadvantages that need to be overcome are the limited lifetime of biological compounds, large-scale production and ease of use.
