                         for electrochemical applications. The fast and dry process 
                         produces graphene oxide tips and oxygen functionalization. The 
                         electrodes are evaluated by cyclic voltametry by 
                         ferri/ferrocyanide redox couple and applied for electrochemical

                         voltammetry. The electrode presents high sensitivity (35.47 
                         uA.uM\−1) and low detection limit (48.3 pM). As far as we 
                         know, this is the lowest LoD in comparison with other works using 
                         CNT or graphene electrodes. The high electrochemical response is 
                         attributable to high density of functionalized edges on carbon 
                         nanotubes tips.",
