Molecularly imprinted polymers as recognition elements in sensors
Résumé
The technique of molecular imprinting allows for the formation of specific recognition sites in synthetic polymers through the use of templates or imprint molecules. These recognition sites mimic the binding sites of biological receptor molecules such as antibodies and enzymes. Molecularly imprinted polymers can therefore be used in applications based on specific molecular binding events, such as affinity separation, assays and sensors, and in organic synthesis and catalysis. The stability, ease of preparation, and low cost of these materials make them particularly attractive. This review focuses on recent developments and advances in the molecular imprinting technique with special emphasis on applications in sensors.
