A sensitive amperômetric sensor for the determination of H2O2 has been constructed.Horseradish peroxidase was successfully immobilized on nano-Au colloids based on the thiol-tailed groups of cysteamine binded to the 2,6-pyridinedicarboxylic acid polymer.With the mediator of the hydroquinone in the solution, the sensor displayed excellent electrocatalytical response to the reduction of H2O2.Compared with enzyme-polymer modified sensor, the immobilization of enzyme was simple and the sensor exhibited a better stability and reproducibility.

Key words: nano-Au colloid, 2,6-pyridinedicarboxylic acid, cysteamine, polymer
