Enhancing the peroxidase-like activity and stability of

Herein, the growth of a partial iron phosphate (FeP) shell with Fe 2+ ions on citrate-capped AuNPs boosted the activity of the AuNPs by up to 20-fold. The FeP-enhanced activity was demonstrated on AuNPs of different sizes, and gold nanostars. When the FeP layer is thick enough to block the access to the Au/FeP interface, the activity was inhibited.
