| Abstract: | Carbon nanodots was prepared using candle soot by an economical and green preparative strategy,and characterized by scanning electron microscopy. The electrochemical sensor was constructed using carbon nanodots modified glassy carbon electrode. The electrochemical behaviors of the sensor were investigated by cyclic voltammetry and differential pulse voltammetry. This sensor showed excellent analytical performance for dopamine detection with detection limit of 0. 02 μmol / L( S / N = 3) and linear range of 0. 1 ~ 100 μmol / L. |
