Abstract: Cobalt phthalocyanine-graphene (CoPc-Gr) complex are fabricated through pi-pi interaction of each components, with CoPc adsorbed/inserted on/in the graphene sheets. The obtained complex could be used in the electro-chemical detection of various medicines. CoPc-Gr modified glassy electrode shows excellent response to the electro-oxidation of dopamine (DA) and ascorbic acid (AA), much better than those of CoPc, graphene oxide (GrO) or graphene (Or) modified electrode. Significantly, the detection of dopamine is a diffusion-controlled process, highly selective, and has a low detection limit and broad linear range.
