The device has dielectric nanoparticles and an electrode trained sensor surface for an internal combustion engine. A counter (4a) and a reference electrode (4b) are arranged and spaced with respect to the sensor surface. A transparent substrate is applied partially on the sensor surface for surface plasma resonance (SPR). A supplementary sensor surface for the SPR is immobilized on the nanoparticles at analyte binding molecules, where the binding molecules are selected from antibodies, peptide aptamers and/or DNA aptamers. An independent claim is also included for a method for detecting an analyte in a sample.
