Abstract
⺠A nanocomposite of MWNT-Chit/PAMAM/DNA modified Au electrode was fabricated. ⺠It was applied to detect DA and UA in the presence of AA. ⺠It exhibited strong catalytic activity toward the oxidation of DA and UA. ⺠It was highly sensitive with detection limit of 0.03 μM DA and 0.07 μM UA. ⺠It surface reproducibility was satisfactory, and it has a long-term stability.
