Copper electroplating and stripping: individual cells FOV. (a) Cyclic voltammogram of Cu deposition and stripping at the graphene electrode in ca 1 mol/L aqueous CuSO4 electrolyte. The voltammogram was obtained at 1 mV/s scanning rate; potential was swept from positive to negative polarity and back. Platinum was used as a pseudo-reference electrode. (b) SEM images and corresponding EDS Cu maps showing deposition and stripping of a copper particle
