The resulting polytyramine film and particles were characterized through scanning electron microscopy, FTIR, cyclic voltammetry and impedance spectroscopy. The modified electrodes exhibited a good sensitivity, reproducibility, and stability. The resulting particles were deposited onto gold electrode through drop casting method. Similarly a new approach was used to chemically polymerize tyramine in an alkaline media using FeCl3 as an oxidant. The electrodeposition was carried out in 0.025M tyramine solution in 0.3 M NaOH in methanol at the voltage ranging from 0V to 1.6 V at the scan rate of 100 mVs-1. The aim of the studies was to modify surface of gold electrode with the layer of polytyramine synthesized through chemical and electrochemical methods. Modifying layers allow scientists to build electrodes with required properties such as for example: selectivity, stability, precision, durability, range of potentials etc. Professor of Colour & Polymer Science University of LeedsĪbstract Developing modified electrodes through electrodepositing conductive polymer layer has been continuous studied in areas such as technology, electronics, medicine, biology and many others.
