摘要：

This work describes the detection of serotonin using a platinum nanoparticlesconductive polymer composite sensing nanomaterial deposited on to glassy carbon electrode. Electrode surface modification with the composite material has been achieved by sinusoidal currents preparation procedure. The sensor displayed a detection limit with a value of 1.9 mu M serotonin. The sensor response was linear for concentrations ranging from 2 to 80 mu M serotonin. The sensor was used in the voltammetric quantification of serotonin in real sample.
