Molecularly imprinted polypyrrole films: Some key parameters for electrochemical picomolar detection of dopamine

► Ultrasensitive imprinted polypyrrole films were prepared for near picomolar electrodetection of dopamine. ► Chronoamperometry was employed for preparing thin polypyrrole MIP films. ► Dopamine recognition by non-imprinted polypyrrole films was unsuccessful hence the specific character of the MIP films. ► The imprinted polypyrrole films are highly selective to dopamine over interferent molecules.
