A simple, easy to fabricate, selective and sensitive sensor for simultaneous determination of nucleic acid bases guanine, adenine and cytosine along with uric acid is being reported. Glassy C electrode with an electropolymerized layer of 4-amino-3-hydroxy naphthalene-1-sulfonic acid could resolve the oxidation peaks of uric acid, guanine, adenine and cytosine using 0.1M NaOH as supporting electrolyte. The electrocatalytic oxidation current is linear in the range from 10 μM-250 μM for uric acid, guanine and adenine and 80 μM-250 μM for cytosine with detection limit 9.31 μM, 0.93 μM, 6.20 μM and 9.20 μM resp. for simultaneous determination by square wave voltammetry. The diffusion coefficient of uric acid, guanine, adenine and cytosine in 0.1M NaOH was determined by chronoamperometry. The electrode processes are diffusion controlled, which eliminate the fouling effect produced by adsorption of these organic compounds on the electrode surface. The developed sensor has promising applications for real sample anal.
