%X In this work, the gold nanoparticles (Au NPs)/multi-walled carbon nanotubes (MWCNTs) composite film modified glassy carbon electrode (GCE) was fabricated, and scanning electron microscopy (SEM) was used to investigate the assemble process of the composite film. In pH 7.0 PBS, a oxidation peak of the vitamin B6 (VB6) was only observed at composite film modified electrode. Under the optimized conditions, the current intensity was linear with the concentrations of VB6 in the range of 1.59 to 102.74 ¦Ìg¡ñmL<sup>¨C1</sup> with a detection limit of 0.53 ¦Ìg¡ñmL<sup>¨C1</sup> (S/N = 3). The modified electrode had been applied in medication analysis, and obtained good results.
