## Abstract Amperometric biosensors incorporating tyrosinase into Teflon/graphite composite were developed for the detection of catechol. The homogeneity of Teflon/graphite was elucidated by means of chronoamperometry (using ferricyanide) and the calculation of the electrochemically active and tota
