Patent Title: Fluorescent polymers and methods for solid-phase extraction
Publication date: 2012
Publication number: US20120171780

Abstract: The apparatus of the present invention comprises a fluorescent polymer contained within a solid-phase extraction (SPE) carrier. The fluorescent polymer is capable of adsorbing an analyte by means of functional monomers. In use of the apparatus, a sample, such as a foodstuff sample, is applied to the fluorescent polymer. If the sample comprises the analyte, adsorption of the analyte onto the fluorescent polymer causes quenching of the fluorescence of the fluorescent polymer. Fluorescence quenching can be detected using a fluorometer or transillumination system. The method can be used to determine whether mycotoxins are present in foodstuff samples.
