Descrição: A new type of amperometric immunosensor for the determination of naphthalene based on self-assemble layer-by-layer technique was reported. The preparation procedure of such a sensor was characterized and the operation conditions, such as the pH value of supporting solution, incubated temperature and time were studied by cyclic voltammetry. Under the optimized working conditions, the current response of the immunosensor was proportional to the concentration of naphthalene in the range of 0.5-100 mu g/L with a detection limit of 0.08 mu g/L(r=0.9986). This method was applied to the naphthalene detection in river water samples and the recovery was ranging in 94.3%-107.0%. The reported immunosensor exhibited high sensitivity and long-term stability for naphthalene detection, and was easy to be prepared and regenerated.
