Selective voltammetric Detection of Dopamine on Gold nanoparticles dispersed polyaniline nanocomposite modified BDD electrode in the presence of ascorbic acid

摘要

The present invention without being influenced by ascorbic acid , gold which can selectively detect dopamine nanoparticles provides an electrochemical sensor using the diamond film electrode peroxide dispersed conductive polymer nanowire . Sensor according to the present invention showed a linearity in a wide concentration range from 0.15 to 500 M, showed a high sensitivity and low detection limit of 0.03 M of 0.131 A / M can detect dopamine . ;
