Biosensor and multiple mycotoxin analysis. Food Control 2003

An immunochemical biosensor assay for the detection of multiple mycotoxins in a sample is described. The inhibition assay is designed to measure four different mycotoxins in a single measurement, following extraction, sample clean-up and incubation with an appropriate cocktail of anti-mycotoxin antibodies. The different mycotoxins could be detected simultaneously in relevant concentrations within a time frame of 25 minutes, in-cluding the time needed for sensor regeneration. The application of the developed assay on presently available miniature SPR devices allows the development for low-cost in-struments, which can be used in field measurements
