Contrasting modulation of enzyme activity exhibited by graphene oxide and reduced graphene.
Here we demonstrate that GO and RGO exhibit contrasting effects on modulation of the peroxidase activity of cyt c. GO could dramatically improve the enzyme activity of cyt c, while RGO showed a strong inhibition effect on cyt c.
