Fig. 4From: An electrochemical sensor based on [Ru(bpy)2dpp]2+/SMWCNTs/Au modified glassy carbon electrode for the detection of 5ʹ-GMPThe Nyquist plot of the impedance spectra of Au/GCE obtained by two different fixation methods (the methods of cyclic voltammetry deposition and drip-coating). Parameters: Einit = 0.255 V, high frequency = 1e+5 Hz, low frequency = 0.01 Hz, amplitude = 0.005 VBack to article page
