A process for detection of mycotoxins, wherein the mycotoxins are selected from the group consisting of aflatoxins, ochratoxins and fusarium toxins, comprises the following steps:a) providing a thin-film waveguide comprising a first optically transparent wave-guiding layer (a) on top of a second optically transparent layer (b), with (b) having a lower refractive index than (a), to which waveguide specific and/or affinity binding partners are immobilized as a chemical or biochemical recognition element for mycotoxins and/or a binding partner in a spatially separated manner, b) applying a mycotoxin(s)-containing sample and binding partners to the immobilized binding partners on said thin-film waveguide, c) detecting a signal in the evanescent field due to the interaction of the binding partners immobilized on the thin-film waveguide with the mycotoxins from the sample and/or with the binding partners. Disclosed are a device for identifying mycotoxins and a kit suitable for carrying out said method. |
