文摘
A disposable electrochemical sensor was developed for dopamine (DOP) determination. Electrochemical overoxidation and poly(pyrrole-3-carboxylic acid) were the modifier. Prepared sensor showed a synergistic effect on the electrochemical oxidation of DOP. Prepared sensor successfully discriminates DOP signal from interfering signals. Analytical application of prepared sensor was successfully tested in real samples.
