Fumonisin is a mycotoxin occurs mainly in maize and derived products. The presence in food or feed constitute a risk to health. The present detection methods for fumonisin are based on immunoafiniteitskolommen (cost price> 10 euros) and carriers of high specificity antibodies. These analyzes are characterized by a high cost price (> 130 euros / analysis), long development time, single use and high analysis time. In addition, the production of antibodies, is time-consuming and expensive. This project is aimed at developing a rapid test (<30 min.), Wherein the fumonisin using molecularly imprinted polymers (as an alternative to antibody technology), and solid phase extraction from the maize (products) is extracted. Is then linked to this, a semi-quantitative assay based on fluorescence detection.
