Self-Assembling of Redox-Active Atrazine Poly(ethylenimine) Conjugates – Interfacial Electrochemical and Spectroscopic Characterization

Abstract : Thin films of polymers tethered with both atrazine haptens and ferrocenyl (Fc) probes were formed on polycrystalline gold electrodes by taking advantage of the facile formation of self-assembled monolayers (SAMs) of thiolates. These films were characterized by polarization modulation Fourier transform infrared reflection – absorption spectrometry (PM-IRRAS), X-ray photoelectron spectroscopy (XPS) and cyclic voltammetry. The combination of these techniques gave a full insight into the structure and the binding mode of the polymers and provided useful quantitative information about both Fc entity and atrazine hapten surface density. This may open the way to a new type of immunosensor for atrazine monitoring.
