✦ Synopsis
is electrochemically deposited on platinum microsize substrate. Two methods are used for the electropolymerization including applying constant potential of 1.65 V to 1.75 V, or cycling the working electrode between two potential limits from ¹0.2 V to 1.65-1.80 V (vs. Ag/AgCl). The resulting conducting polymer electrode is used for the determination of some organic molecules of biological interest. The resolution of the voltammetric peaks obtained for the determination of a mixture of three components analyte is a function of the method used for electrodeposition of the polymer film. The electrochemical data obtained at the microsize conducting polymer electrode are compared to those obtained at ''conventional''-size polymer electrodes. The morphology of the microsize polymer electrode is examined using scanning electron microscopy. The data suggest great promise for using microsize polymer electrodes as electrochemical sensor for biomedical applications.
