Molecular imprinted polymer for hazard compounds detection

AbstractNowadays environmental monitoring of hazardous small molecules such as pesticides, drugs, toxics...etc at very low concentration levels remains a challenge for the scientific community. We will discuss an emerging approach that address this challenge based on magnetic nanoparticles (MNP) decorated with molecularly imprinted polymers (MIPs). MIPs are synthetic materials endowed with highly cross-linked three-dimensional network binding sites. These polymers facilitate high sensitivity targeting a specific analyte relying on functional monomers such as ethylene glycol dimethacrylate or pyrrole, in order to create a template molecule. Composites made of MIPs build onto MNP bring several advantages as sensing platform since their synergy and properties allow manipulation of the analyte in a selective way as well as a label-free detection via electrochemical impedance spectroscopy. Furthermore, they offer a rapid and simple alternative as filtration or centrifugation processes are not required. We will describe the synthesis and characterization of two proposed hybrid material. On the other hand, we will explore and report the application of both composites in chemical contaminants detection in environmental samples such as seawater.
