Experimental methods Synthesis of Fe O RGO NSCs and Fe
Fe3O4/1% RGO NSCs, Fe3O4/3% RGO NSCs and Fe3O4/5% RGO NSCs was dispersed in DMF (1 ml) separately with ultra-sonication for 10 min to obtain AICAR homogenous suspension. Then, 5 μl of the homogenous suspension was dropped onto the surface of polished glassy carbon electrode (GCE) and dried at room temperature.
