This contribution describes the development of an impedimetric immunosensor for atrazine detection. This
immunosensor is based on the use of interdigitated metallic
μ-electrodes (IDμEs) The method described in this work does not use any redox mediator and relies on the direct detection of
immunochemical competitive reaction between the pesticide and
a haptenized-protein immobilized on interdigitated
μ-electrodes for the specific antibody.
The immunoreagents used were specifically developed to detect atrazine. The immunochemical detection of this pesticide is achieved without using any label. The immunosensor shows a limit of detection of 8.34±1.37 μg L-1, witch is lower than the Maximun Residue Level (MRL) (50μg L-1)established by EU (European Union)for residues of atrazine as herbicide in the wine grapes and other foodstuff products.
