Abstract

Due to the high peroxidase-like activity and small lateral size of graphene quantum dots (GQDs), the covalently assembled GQDs/Au electrode exhibits great performance and stability in H₂O₂ detection. It is better or comparable to some enzyme-immobilized electrodes, and thus could be useful in sensing H₂O₂ changes in biological systems.
