Gold nanotadpoles were synthesized by a simple temperature-reducing seeding approach. A novel gold electrode modified with gold nanotadpoles through a sulphydryl-terminated self-assembled monolayer was then fabricated and exhibited strong promoting effect toward the electrochemical oxidation of dopamine (DA). The anodic peak currents obtained from the cyclic voltammetry (CV) were linearly dependent on DA concentration over the range of 3 x 10(-5)similar to 1.8 x 10(-4) M with correlation coefficient of 0.999. The detection limit obtained was 0.1 mu M. It was also successfully used for the selective detection of DA in the presence of ascorbic acid (AA). This modified electrode showed good selectivity and recovery.
