Abstract
Electrochemical molecularly imprinted polymers (e-MIP) are MIP specially designed to detect organic molecules thanks to the electrochemical answer of a redox probe inserted inside the binding cavities of cross-linked MIPs. Herein, e-MIP microbeads particles were synthesized from ferrocenylmethyl methacrylate and 4-vinylpyridine functional co-monomers, bisphenol A (BPA) as the target and ethylene glycol dimethacrylate as cross-linker. In addition of the role of monomer, ferrocenylmethyl methacrylate acts as a redox probe enabling the electrochemical detection of the target. After physicochemical characterization, e-MIP microbeads were incorporated in a graphite-hydroxyethylcellulose composite paste to prepare screen-printed carbon electrodes (SPCE). Electrochemical properties of e- MIP-SPCE revealed a highly sensitivity in the presence of BPA in aqueous medium compared to the corresponding non imprinted polymer (e-NIP-SPCE) with a limit of detection (LOD) of 0.06 nM.
