Résumé	A sensitive and selective electrochemical method for the determination of dopamine using a combined electropolymerized permselective film of polytyramine and polypyrrole-1-propionic acid on a glassy carbon (GC) electrode was developed. The formation of a “layer-by-layer” film has allowed for selective detection of dopamine in the presence of 3,4-dihydroxyphenylalanine (L-DOPA), DOPAC, ascorbic acid, uric acid, epinephrine and norepinephrine. The modified electrodes exhibited a detection limit of 100 nM with linearity ranging from 5 x 10⁻⁶ to 5 x 10⁻⁵ M. No cleaning step was required during the course of repeated measurement.
