Cobalt phthalocyanine-graphene(CoPc-Gr) complex are fabricated through π-π 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(Gr) modified electrode.Significantly,the detection of dopamine is a diffusion-controlled process,highly selective,and has a low detection limit and broad linear range.
