Abstract : This work reports an electrochemical sensor for the quantification of the analyte, Tyramine. The 5-Amino-1-naphthol monomer is used to modify a PGE by electropolymerisation, which is used to develop the sensor. Utilizing SEM examination, Infrared Spectroscopy, cyclic voltammetry, and EIS, the morphological and electrochemical characterizations of the modified electrode were carried out. Using differential pulse voltammetry, the oxidation peaks of Tyramine is measured at potentials of 0.596 V. The linear range for Tyramine was observed from, 100 nM to 50 μM and 50 μM to 600 μM with an LOD of 89.8 nM with high sensitivity. As a result, food sample investigations may make use of this innovative, manufactured electrode.
