Dopamine is an important neurotransmitter and plays a vital role in the proper functioning of human metabolism. Therefore, fabrication of a sensitive sensor for the detection of dopamine is crucial. The work reports detection of dopamine in presence of interfering ascorbic acid, uric acid, Na+, K+, Ca2+, urea and glucose. The linear range for the detection of dopamine is observed from 1.07x10(-4) M to 2.19x10(-4) M in presence of 1.00x10(-3) M ascorbic acid and 1.00x10(-3) M uric acid. The detection limit is estimated to be 1.46x10(-8) M.
