MOLECULAR IMPRINTED POLYMERS PREPARED BY ELECTROPOLYMERIZATION OF NI-(PROTOPORPHYRIN-IX)

The features of combining a chemically modified electrode (CME) with a n artificial receptor system, prepared by imprinting electropolymerize d [Ni-(Protoporphyrin IX) dimethyl ester] [Ni-(PPIX)] in the presence of nitrobenzene, were studied. The responses of the modified glassy ca rbon electrode towards template molecules were analyzed by cycling ove r the nitrobenzene reduction wave. The specific signal was much higher than the non-specific one which demonstrates the selectivity of such a system. This approach has potential for preparation of selective pol ymeric films on the surface of different transducers.
