dc.description.abstract [EN] A sensitive, simple and label-free immunosensor for atrazine detection was developed. The immunosensor was based on antibody physisorption as immobilization technique. This technique was proposed as a cost-effective gold immuno-functionalization strategy alternative to SAM-based strategy for pesticide detection. Each step of immunosensor construction was characterized by electrochemical impedance spectroscopy, and the antibody-atrazine interaction was measured in a dynamic range from 10 to 150 ng/mL. This method was highly selective for atrazine and propazine, showing weak or no cross-reactivity to other similar compounds like terbutylazine. A limit detection of 10 ng/mL of atrazine was detected in PBS buffer with a good reproductibility. Lower limit detection in tap water was obtained. es_ES
dc.description.sponsorship This work was financially supported by the PCI cooperation project between Spain and Tunisia. The authors thank Dr. F. Del Campo and Dr. E. Baldrich from CNM-Barcelona (Spain) for the interdigitated microelectrode fabrication. Pr. A. Abdelghani has to thanks the NATO (North Atlantic Treaty Organization) for the material donation. en_EN
