Fig. 4From: Co-immobilization of laccase and TEMPO onto amino-functionalized magnetic Fe3O4 nanoparticles and its application in acid fuchsin decolorizationCyclic voltammetry of PVA/Fe3O4-Laccase–TEMPO GC (a) and PVA/Fe3O4-Laccase GC (b). The anodic peak potential of PVA/Fe3O4-Laccase–TEMPO modified GC electrode shifted to a more positive value and the cathodic peak potential shifted to a lower negative directionBack to article page
