Fig. 7From: An electrochemical sensor based on [Ru(bpy)2dpp]2+/SMWCNTs/Au modified glassy carbon electrode for the detection of 5ʹ-GMPCV curves of [Ru(bpy)2dpp]2+/SMWCNTs/Au/GCE in the solution of pH = 3 0.1 mmol L−1 5ʹ-GMP with different preconcentration time (in the range of 0 to 400 s). Parameters: v = 100 mV s−1, Erange = from 0.6 to 1.5 V, precondition potential = 0.6 VBack to article page
