BACKGROUND

Molecular Imprinted Polymers and Ion Imprinted Polymer are well known to have a high power of molecular recognition and present highly stable imprinted cavities. The originality of the approach is the integration of an electrochemical probe within the structure of the MIP to form a Redox-MIP compound with increased detection sensibility. The detection based on a close interaction between the target and the electrochemical tracer will combine the high power of recognition of MIP/IIP to the advantages of electrochemical detection in terms of low cost, facility of use, and sensibility.

KEY BENEFITS vs. STATE OF THE ART

The “continuous control of water” is managed by European Committee of Standardization (AFNOR-T90L French committee). These new quality standards increase the need of real-time sensors development to detect specific pollutants over relevant sanitary thresholds. Since fifty years many biosensors have been developed for environmental monitoring and assessment. The transduction can be based on electrochemical, optical, or other physical techniques. In all cases, problems are : specificity, stability, limit of detection and cost. The invention can allow to develop real-time sensors with electrochemical detection (low cost, miniaturization, real-time answers).

Development Status

ANR submitted to developspecific real-time sensors for specificpollutants (BaP, mycrocystine, lead).

APPLICATIONS

• Water environment control

Electrochemicalsensor for real-time detection of chemical substances (organicmoleculesand ions) in water effluents.

• Solid support extraction
