Abstrakt

Molecularly Imprinted Conducting Polymer based films (MICP films) devoted for the taurine determination is described. MICP films were electrodeposited from an aqueous solution containing 3,4-ethylenedioxythiophene, acetic acid thiophene, flavin mononucleotide, and taurine. The presence of taurine inside freshly deposited MICP films as well as absence of taurine in the outer layer of the MICP film after extraction process was confirmed by the XPS spectra. It was found that after taurine extraction, MICP films can be used as a potentiometric sensor giving close to Nernstian response towards taurine equal to 53.8 ± 2.6 mV/p[taurine] in the concentration range 10−2 to 10−4 mol·dm−3.
