| Abstract: | Aligned carbon nanotubes(ACNTs) were synthesized on a carbon fiber(CF) substrate,and the resulting CF-ACNT complex was used for microelectrode fabrication and 5-HT detection.The CF-ACNT microelectrode displayed good electro-catalysis for 5-HT,thus detection was sensitive.Non-special adsorption of 5-HT oxidization products to the CF-ACNT electrode was resolved using potentiostatic methods with the electrode recovering favorably. |
