主　　题：electrochemiluminescent sensor chemical modification luminol cysteine sensitization superoxide dismutase 

摘      要：In the phosphate buffer solution of pH7,the cysteine sensitized the electrochemiluminescence (ECL) of *** could be modified on the surface of platinum electrode and furthermore adsorbing the luminol on its exterior to construct an ECL *** ECL intensity of this sensor was strong enough and very *** wasn t obvious decrease of ECL intensity for thirty times of using in 48 hours with the relative standard deviation (RSD) of 0.98%.It could be used to determine some quenching effective molecules such as superoxide dismutase (SOD) with negative response upon the concentration range from 4.8 IU/ml to 57.6 IU/ml.
