Molecularly Imprinted Polymers (MIPs) are new materials used for the detection of pollutants in aqueous medium. These materials use a three-dimensional interactive conformation created by copolymerization of monomers around a template molecule. Once the template removed, the resulting polymer keeps the memory of the template via specific recognition sites. This makes it possible to introduce them as recognition phases in sensors for the monitoring or detection of pollutants in aqueous medium.
The originality of this work is to introduce a redox probe directly in the MIP during its synthesis to associate the principle of their recognition performances with a cheap and useful electrochemical detection technic: the cyclic voltammetry. By this way, a decrease of current signal of redox probe is observed when the polymer traps the template.
In this work, Bisphenol A known to be a toxic and endocrine disruptor is used to validate the electrochemical MIPs principle. The detection of the Bisphenol A by this strategy could be useful and pave the way toward detection of others pollutants.
