Enhancement of antioxidant activity of well-dispersed core-shell structured CeO coating Au nanorods under visible light irradiation.

Gold nanoparticle (AuNP) modification shows great advantages in improving the antioxidant activity of nanoCeO. However, the improved effect of AuNP modification becomes smaller and even results in the decrease of antioxidant ability due to severe aggregation with increasing nanomaterial concentration. Additionally, the effects of photo-properties of AuNPs on the antioxidant activity of nanoCeO have not been studied.

Surface plasmon resonance biosensor for the accurate and sensitive quantification of O-GlcNAc based on cleavage by β-D-N-acetylglucosaminidase.

Abnormal O-linked-N-acetylglucosamine (O-GlcNAc) concentrations have been associated with a variety of diseases (e.g., cancer, Alzheimer's disease, cardiovascular disease, etc.

The effect of DNA on the oxidase activity of nanoceria with different morphologies.

Many nanomaterials have been reported to have enzyme-like activities and are considered as nanozymes. As a multifunctional nanozyme, nanoceria has received much attention due to the dual oxidation states of Ce/Ce which facilitate redox reactions at the particle surface. Despite the advantages of nanozymes, their limited activity and lack of enzyme specificity are still problems to be resolved.
